Soil Stabilization by Using Lime and Fly Ashijtsrd
For any type of structure, the foundation is very important and it has to be strong to support the entire structure. In order for the strong foundation, the soil around it plays a very critical role. To work on soils, we need to have proper knowledge about their properties and factors which affect their behaviour. By consolidating under load and changing volumetrically along with seasonal moisture variation, these problems are manifested through swelling, shrinkage and unequal settlement. In this paper the experimental results obtained in the laboratory on expansive soils treated with industrial waste fly ash and lime are presented. A study is carried out to check the improvements in the properties of expansive soil with fly ash and lime in varying percentages. The test results such as liquid limit, standard proctor and differential free swelling test obtained on expansive clays mixed at different proportions of lime and fly ash admixture are presented and discussed in this paper. The results show that the stabilized clay has lesser swelling potential whereas an increase in optimum moisture content has been observed. P. Bala Krishana | G.

Soil Stabilization using Fly Ash and Cotton Fiberijtsrd
Mixing of fiber for ground improvement has been practiced for recent years. Many researches has shown the expected results. This paper mainly deals with the ground improvement technique using both Fly Ash and cotton fiber. The combination of them gives a satisfactory value of its practical application. Both Fly Ash and Cotton fiber are treated as waste materials in our country in spite of having its engineering significances. Here all the tests were performed accepting the Fly Ash percent is 10 for maximum bearing capacity of soil. Three types of sample were prepared as per 0.3%, 0.5%, 0.7% of cotton fiber. For instances, it deliberately increases the Dry Density of soil up to 48.05 KN/m3 where as normal unreinforced soil sample gives about 22 KN/m3. The Ultimate bearing capacity increases up to 80.65 Kpa whereas the unreinforced soil sample gives for 35 Kpa. The result of California Bearing Ratio (CBR) test gives desired value (23%) than unreinforced soil (17%). The CBR test is performed only for 0.7% of cotton fiber where maximum stress is found. The most significant part in this study is to show the variation on cotton fiber for ground improvement technique at different ratio. This paper shows the gradual increase in Deviator stress for UCS tests for the increase in the percent of cotton fiber mixing with Fly Ash. This research may meet the need of ground having low strength at important sites.

Bearing Capacity of High Density Polyethylene (HDPE) Reinforced Sand Using Pl...IJERA Editor
The work presented here is a study to examine the improvement in bearing capacity of coastal sand of Trivandrum, Kerala, India using high density polyethylene (HDPE) /woven fabric as reinforcement in discrete layers. The bearing capacity was evaluated using plate load test. The effect of reinforcement configurations like sheet reinforcement (sanded with adhesive, with adhesive and sheet alone) and strip reinforcement (single and grid pattern) are investigated. The test parameters chosen for the present study are, depth of topmost layer of reinforcement layer below footing, compacted density and number of layers of reinforcement etc. From the tests, it has been observed that sheet reinforcement is more effective than sheet sanded with adhesive and strip reinforcements. It is found that the synthetic adhesive gives no binding action at the interface of the reinforcement and soil. But it is to be noted that the sheet with adhesive dried has a marked influence on the bearing capacity especially at lower densities. The strip reinforcements in single pattern is considered to be a favorable choice for minimum reinforcement. The strip reinforcement in single or grid pattern gives sufficient improvement in strength.

An Experimental Study of Soil Stabilization with Cement and Polymerijtsrd
The aim of the study was to determine the value of Unconfined compressive strength and CBR values of Soil after stabilizing it with Cement and Polymer. Soil stabilization has been widely used as an alternative to substitute the lack of suitable material on site. The utilization of nontraditional compound stabilizers in soil improvement is developing every day. In this investigation a lab try was led to assess the impacts of waterborne polymer on unconfined pressure quality on sandy soil and CBR Test on clayey soil .The lab tests were performed including grain size of sandy soil, unit weight, and unconfined compressive quality test. The sand and different measures of polymer 2 , 3 , and 4 and concrete 20 , 30 , and 40 were blended in with every one of them into mixture utilizing hand blending in research center conditions. The examples were exposed to unconfined pressure tests to decide their quality following 7 days of restoring. The consequences of the tests showed that the waterborne polymer fundamentally improved the unconfined pressure quality of sandy soils which have weakness of liquefaction. Polymer altered the building properties of soil through physical holding. The amount of polymer required to modify the engineering properties was directly related to specific surface and soil particle coating thickness. Polymer amended soils displayed a reduced performance compared to cement amended soils.

Estimates of Elasticity and Compressive Strenght in Soil Cement Mixed With Ij...AM Publications
Similar to concretes, soil cements have increasing strengths with age. More importantly, this type of material has lower elasticity comparatively to solely soils. Being used as road foundation materials, soil cements may have sufficient strength to support loads from vehicles. However, in a long run, repetitive loadings, such as those from vehicles, may damage soil cements foundations signified by cracking. To address this limitation, palm sugar fibers have been added to the soil cement mixture. It is found that fibers can increase the elasticity of soil cements. This study has also provided results of compression strength tests conducted in soil mechanic laboratory over 30 (thirty) remolded cylindrical samples of soil cements that have different ages, e.g., 3, 7, 14, 21, and 28 days, respectively. The samples are reconstructed of type SC soils, type I cements, and palm sugar fibers. The amounts of cement are 6% and 10% by weight of dry soils, while the portion of palm sugar fiber is 0,5% by weight of dray soils. Before being tested, the samples are stored under a constant temperature. Last but not least, the data series obtained from these tests are analysed and results in an important expression that can be used for estimating the compression strength and elasticity module of soil cements added with palm sugar fibers. Last but not least, the data series obtained from these tests are analysed and results in an important expression that can be used for estimating the compression strength and elasticity modulus of soil cements mixed ijuk-aren. The results obtained is empirical equation models forecast increased compressive strength and modulus of elasticity of soil cement mixed ijuk-aren.

Prediction Models for Estimation of California Bearing Ratio for Cohesive Soilijtsrd
Cohesive soils are well known for their low strength properties. Thus, they are inappropriate for geotechnical works. Soils may be stabilized to increase strength and durability. Stabilization with cement is a common treatment technology. The present study examines the strength of cement stabilized soil. The laboratory tests were carried out in order to study the strength of california bearing ratio (CBR). Nine clayey soils with different properties were mixed with various amounts of cement content (3, 6, 9 and 12%) and compacted at the optimum moisture content and maximum dry density. Soaked or unsoaked condition of soil affects the CBR value. The test results show that unsoaked CBR before stabilization ranges between 2.78% and 10.22% which that of its corresponding soaked samples range between 1.01% and 9.5%. After stabilization, the values of unsoaked CBR range between 3.08% and 47%. The maximum values of unsoaked CBR are within 10.8% to 47%. So it can be used as sub-base condition.

OPTIMUM USE OF POLYPROPYLENE FIBERS IMPROVES SOIL PROPERTIES IAEME Publication
Soil being the cheapest and readily available construction material has been popular, even though it suffers from being poor in mechanical properties. It has been the constant endeavor of research workers to put forth innovative ideas to improve its mechanical properties to suit the requirements of engineering structures, Vidal in 1968 postulated the new oriented concept of reinforced earth technique. Reinforced earth is a construction material composed of soil fill, strengthened by inclusion of rods, bars, fibers or nets that interact with the soil by means of frictional resistance and act as a coherent mass. It is used in a variety of applications such as retaining structures, embankment, stabilization of subgrade and improvement of soil beneath pavements and footings. Fiber reinforcement technique permits use of natural as well as synthetic fibers for soil reinforcement. In Maharashtra black cotton soil is found in abundance which is highly expansive soil. In present study an attempt has been made to investigate the use of polypropylene fibers for improving properties of locally available soil. The comparison of properties of soil with addition of varying percentages of fibers by dry weight of soil and having different aspect ratios is also carried out. The addition of polypropylene fibers resulted in increase in optimum moisture content and decrease in maximum dry density. Direct shear tests conducted on soil shows increase in value of cohesion and decrease in value of angle of internal friction. With the inclusion of the fibers increase in C. B. R. value and unconfined compressive strength is observed.

The alkali-aggregate reaction (AAR) occurs when alkalis, typically sodium and potassium ions from cement, reacts with minerals present in aggregates within concrete.This reaction can lead to the formation of a gel, which can induce swelling and exert pressure on the concrete, ultimately resulting in the expansion and, in severe cases, the cracking of the structure. The detrimental consequences of this reaction become more pronounced over time, potentially compromising the structural integrity of the concrete.

=== Investing In The US As A Canadian… And How To Do It RIGHT!! (feat. Erwin Szeto) ===
Ever been curious about Real Estate Investing in the US?? At Volition, for the past 14 years, we have been focused on helping investors invest in over $250M of real estate and generate $100M of wealth in the Toronto market, but we are always open to learning more about other business models and learning from other investors.
The US has always been an intriguing market to invest in. But the US is a big place… if you’re interested in investing in the US, you probably have a lot of questions, like:
☑️ Specifically WHERE should you invest?
☑️ What are the best markets to invest in and why?
☑️ How much are property prices there?
☑️ What are the returns like?
☑️ What is cashflow like?
☑️ Compared to investing in Toronto or other cities in Ontario, what are the benefits / tradeoffs?
☑️ What ownership structure should I use?
☑️ What are the tax implications?
☑️ Can I get financing?
☑️ What are tenants like?
Enter Erwin Szeto, a longtime friend of Volition. Since 2005, Erwin Szeto and his team have navigated the challenging landscape of being landlords in Ontario. Now, they are shifting their focus and guiding their clients' investments toward the more landlord-friendly environment of the USA. This decision comes after assisting Canadian clients in transacting over $440,000,000 in income properties. Faced with issues like affordability constraints, tenant-friendly laws, rent control, and rental licensing in Canada, Erwin sees a clear opportunity in the U.S. Here, there is a significant influx of investments leading to the creation of high-paying manufacturing jobs. Erwin and his clients are poised to capitalize on these opportunities where landlord rights are stronger and there is no rent control.
To facilitate this transition, Erwin has partnered with and become a client of SHARE, a one-stop-shop U.S. Asset Manager. Founded by Canadians for Canadians, SHARE enables as passive an ownership experience as possible for landlords in the U.S., while still maintaining direct, 100% ownership.

https://www.constrofacilitator.com/polypropylene-fiber-reinforced-cohesive-soil/ 1/11
Polypropylene Fiber Reinforced Cohesive Soil
Polypropylene reinforcement is a common method of strengthening soil. The aim of the present study
is to understand the behavior of randomly distributed discrete polypropylene reinforced cohesive soil
subjected to different strain rates. Unconsolidated undrained triaxial tests were conducted with 5
different polypropylene contents (0, 0.1, 0.2, 0.3 and 0.4 % by dry weight of soil) at 4 different strain
rates (0.5, 1, 3 and 6 %/minute). For unreinforced soils, the failure deviator stress initially increased,
then either decreased or remained constant with increase in strain rate. But for reinforced soil, the
stress values showed an increasing trend with rise in strain rate. It was found that for reinforced
soils, the failure deviator stress was minimum and maximum corresponding to 0.5 and 6 %/minute
strain rates respectively. With increase in rate of strain, the value of cohesion initially increased and
then decreased beyond an optimum value of reinforcement for most of the cases. The value of angle
of internal friction did not show any specific trend corresponding to the change in strain rates.
Introduction
Reinforcing a soil mass is an efficient and proven technique to improve its engineering properties. The
principal aim of incorporating reinforcement in soil is to improve the bearing capacity and stability,
and to decrease the deformations and settlements. Polymer such as polypropylene (PP) reinforcement
in the form of discrete fiber is a popular and well established method of soil reinforcement. PP fibers
are used to increase shear strength, to minimize volumetric shrinkage and swelling of soil. The
preponderance of published research work is about the effect of randomly distributed fibers on
enhancing the properties of cohesionless soils [1-7]. Some of the noteworthy investigations on the
strength behavior of fiber reinforced fine grained soils are by Freitag [8], Nataraj and McManis [9],
Puppala and Musenda [10], Tang et al. [11]. Zaimoglu and Yetimoglu [12] investigated the behavior
of polypropylene reinforced fine grained soil and reported that the unconfined compression strength
tended to increase when the fiber content was increased. Masoumi et al. [13] carried out
improvement of soft soil with both polypropylene fiber and polyvinyl acetate resin. Sharma [14] used

waste polypropylene fiber and cement kiln dust to improve strength of clayey soil. It was found that
upon addition of fibers, unconfined compressive strength and California bearing ratio increased
appreciably.
One of the most important factors controlling the strength of soil is the strain rate to which the soil is
subjected [15-18]. The responses of the soil get affected if the loading time/ strain rate changes.
Previously, investigations had been performed to observe the influences of strain rate on effective
stress parameters [19], undrained strength {20], and stiffness [21] of soils. Building up of pore
pressure at low strain rate (and constant moisture content) was opined to be a crucial parameter for
strength reduction [17]. Abraham et al. [22] observed the influence of strain rate on the strength
parameters of clay. It was found that there was a rise in undrained strength as the strain rate
increased in triaxial tests. Martindale et al. [23] investigated the response of a strain rate dependent
clay constitutive model with parametric sensitivity and uncertainty quantification. Alam et al. [24]
investigated the behavior of sandstone under different strain rates in uniaxial loading. The failure
strain and the modulus of elasticity increased with increase in strain rate. Enomoto et al. [25]
conducted a series of drained triaxial compression tests to evaluate the rate-dependent stress-strain
behavior of gravelly soils.
Until now, few studies have been conducted to observe the behavior of polymer reinforced soil at
different strain rates. But, in practical cases, there may be variations in the time during which the
load is applied or there may be variations in strain rates; hence the strength and deformation
characteristics/ behavior of the soil-fiber matrix will be affected. The principal objectives of this study
are to investigate the effect of strain rate on strength of cohesive soil reinforced with randomly
distributed discrete polypropylene fibers and to establish the correlation between strain rate, polymer
content, deviator stress, cohesion and angle of internal friction.

The soil sample was collected locally from Mesra, Ranchi, Jharkhand in India. Soil lumps were broken
into small pieces and was screened through a sieve of 4.75 mm aperture to segregate the soil from
pebbles, roots etc. The properties of soil are enlisted in Table 1. The soil was classified as “ML” and
“MI” according to USCS [26] and IS: 1498-1970 (Reaffirmed 2007) [27] respectively. Polypropylene
fibers of 0.05 mm thickness, 2.5 mm width were collected from local market and cut to 5 mm length
and were used as reinforcement. The properties of polypropylene are presented in Table 2.

The soil was mixed with the randomly distributed discrete polymer fiber in different proportions (0,
0.1, 0.2, 0.3, and 0.4 %) and Standard Proctor tests were conducted to determine the maximum dry
density and optimum moisture contents. The results are shown in Table 3. These showed that with
increase in percentage of reinforcement, both maximum dry density as well as the optimum moisture
content decreased. The fall in dry density may be attributed to the reduction of average unit weight of
solids [28] i.e. mixture of soil and fiber with increase in fiber content. Also, the reduction in optimum
moisture content might have happened due to drop in water absorption capacity of the soil-fiber
matrix with increase in quantity of fiber.

Soil samples for triaxial tests were prepared by initial dry mixing of oven dried soil and the
corresponding quantity of randomly distributed discrete fiber (0, 0.1, 0.2, 0.3, and 0.4 % by weight
of oven dried soil). Then water was added to the mix according to the optimum moisture content as
per the results obtained from standard proctor test. Unconsolidated undrained triaxial tests were
conducted with samples having 38 mm diameter and 76 mm height at cell pressures (σ ) of 70, 140,
210 kPa to get the values of cohesion and angle of internal friction of reinforced and unreinforced soil.
Behavior of soil (reinforced and unreinforced) at four different strain rates of 0.5, 1, 3, and 6
%/minute were observed. As per “ASTM D 2850 – 95 (Reapproved 1999) – Standard test method for
UU triaxial compression test on cohesive soils” [29], strain rates of approximately 1 %/minute and
0.3 %/minute may be used for plastic soil and brittle soil (such as soil with very low water content)
respectively. In the current investigation, though the soil specimen was not brittle, still experiments
were conducted under 0.5 %/minute strain rate to have an idea of the behavior of the soil at such a
low rate. High strain rates such as 5 %/minute are used to evaluate the response of soil under
various field conditions for example fast installation process of pile and projectile penetration, rapid
application of surcharge, rapid excavation, aircraft wheel loading on runways etc. [Sudan and Sachan
(2017)].
The deviator stress –strain responses, variation in cohesion and angle of internal friction for different
polypropylene proportions and strain rates were observed. In all experiments, failure deviator stress
was considered as the stress corresponding to an axial strain of 15 % as per “ASTM D 2850 – 95
(Reapproved 1999) – Standard test method for UU triaxial compression test on cohesive soils” [29],
or corresponding to physical failure of the sample, whichever occurred earlier.

Results and Discussions
Characteristics of Stress-Strain Curves and Variation in Failure Deviator Stress
Typical plots of deviator stress-axial strain for unreinforced soil are shown in Figure 1. It was found
that the failure deviator stress corresponding to 0.5 % /minute strain rate was least. As the strain
rate increased from 0.5 to 1 % /minute, the stress values (corresponding to a particular magnitude of
axial strain) also increased. In experiments
Fig. 1 Typicalstress-strain curves for unreinforced soil
performed at a slower rate of strain, comparatively more time had been permitted for structural
breakdown, hence a higher pore pressure at failure was generated leading to decreased strength.
Again, on increasing the rate of strain from 1 to 3 %/minute, deviator stress decreased in general, or
almost remained equal (to stresses corresponding to 1 %/ minute); this probably happened due to
disintegration of the inter particle bond at higher strain rate. On increasing the strain rate from 3 to 6
%/minute, the stress went down further. For axial strain up to about 8 %, the stresses were even
below than those corresponding to 0.5 %/minute strain rate. This was also caused due to breakage of
inter particle bond at elevated rate of testing. To summarize the above behavior, it may be said that
the magnitude of the stress depends on the combined effects of generation of excess pore pressure
at lower strain rate, as well as on disintegration of particle bonds at a higher rate of strain.
For reinforced soils, irrespective of polypropylene percentage, the failure deviator stress was
minimum and maximum corresponding to 0.5 %//minute and 6 %/minute strain rates respectively.
Typical plots for above are shown in Figure 2. In this case, breaking of inter particle bond at higher
strain rate was outdone by the strength induced by the fibers. Also, in the majority of the
experiments conducted with polypropylene reinforced soil no definite peak of stress was reached even
at 15 % axial strain. This could be a manifestation of the ductile behavior induced by the fiber
inclusions.

The percentage increase in deviator stress with reference to 0.5 %/minute strain rate (corresponding
to the same cell pressure) are shown in Table 4 (a) to Table 4(e). It may be seen from Table 4 (a)
that for soil without reinforcement and cell pressure (σ )= 70 kPa, the increase in deviator stress
corresponding to 1, 3, and 6 %/minute strain rate were almost same and above 90 % in each case.
The magnitude of rise of stress for σ = 210 kPa were comparatively less (around 10 to 20 %)
corresponding to different rate of strain (1, 3, and 6 %/minute). The increase in deviator stress was
highest (119.87 %) at cell pressure of 140 kPa (3 %/minute). Table 4 (b) indicates that for 0.1 % PP
reinforcement, the deviator stress increment was as low as 6.72 % (σ = 210 kPa, 1 %/minute strain
rate), and as high as 162.28 % (σ = 70 kPa, 6 %/minute strain rate). For 0.2 % PP and 3 %/minute
strain rate, as it may be seen from Table 4 (c), with a two-fold increase in cell pressure from 70 to
140 kPa, the percentage rise of stress was also almost doubled i.e. from 40.58 % to 80.72 %. Table 4
(d) reveals that with 0.3 % PP and 1 %/minute rate of strain, for a three-fold rise in σ (70 to 210
kPa) the corresponding percentage increment magnitude of deviator stress enhanced about one-and-
half times (from 31.93 % to 45.07 %). Table 4 (e) shows that with 0.4 % PP, the peak percentage
increase in stress (64.37 %) occurred for 6 %/minute strain rate and σ = 210 kPa.

Effect of Strain Rate and Reinforcement on Cohesion
Figure 3 shows variation of cohesion with polypropylene contents at different strain rates. For
unreinforced soil, in the present study the cohesion corresponding to 0.5 %/minute was much lower
as compared to the value of the same for increased strain rates. This was associated with low value
of deviator stress for 0.5 %/minute. Indeed, there may be a threshold value of rate of strain up to
which the deviator stress / cohesion is considerably low. Further investigations are needed to throw
more light on it. For unreinforced soil, corresponding to increase in strain rate from 1 to 3 %/minute,
the cohesion remained almost same; and on increasing the rate from 3 to 6 %/minute the
corresponding increase in cohesion was about 10 %. It could also be seen from Figure 3 that for
strain rates of 0.5, 3, and 6 %/minute the value of cohesion initially increased and later reduced with
increase in polymer content. It may be opined that there was an optimum value of fiber content
corresponding to the maximum magnitude of cohesion, beyond which the cohesion reduced with
increase in fiber proportion. The possible reasoning for above was that with greater fiber content, the

mass of soil matrix became less than sufficient to develop a proper bond between soil and polymer
causing inferior mixing and balling of fiber. Corresponding to strain rate of 1 %/minute the cohesion
intercept varied with fiber content like a saw blade. Probably, the same might have happened due to
uneven distribution of fibers when tests were done with higher quantity of reinforcing polymer.

Effect of Strain Rate and Reinforcement on Angle of Internal Friction
The variation of angle of internal friction did not show any particular pattern (Figure 4). At strain rate
of 1 %/minute it showed a zig-zag type variation which was similar to the behavior asobserved by
Zaimoglu and Yetimoglu [12] for the same strain rate. The highest and lowest values of angle of
internal friction were 18° (corresponding to 0.4 % fiber content, 6 %/minute strain rate) and 6.5°
(corresponding to 0.1 % fiber content, 1 %/minute strain rate) respectively. Further investigation is
recommended to understand the nature of variation of the friction angle.

Conclusions
In the present study extensive laboratory experiments were conducted with unreinforced and discrete
polypropylene fiber reinforced ML [26] soil under varying strain rates. It was observed that at higher
strain rate, for unreinforced soil, due to the disintegration of inter particle bond strength reduced.
But, in the case of reinforced soil, the addition of fiber vanquished the effect of above breakage of
particle bonding; and the failure deviator stress increased with rise in strain rate. This happened due
to build up of greater pore pressure in slow test. For 0.5, 3, and 6 %/minute strain rates, with
increase in polymer content initially the cohesion increased then decreased. But for 1 %/minute rate
of strain the value of cohesion showed a zig-zag variations. A limitation of this study was that only
one length (5 mm) had been considered for reinforcing the soil. It may be mentioned here that no
literature could be found reporting the behavior of polymer reinforced soil at different strain rates,
and due to lack of literature the responses observed in the present investigation could not be verified.
But, the present findings would serve as a benchmark for future studies.
