This report presents a study on the effect of partial replacement of coarse aggregates by rubber tyre aggregates on the property of concrete. Utilizing the waste rubber tyers in the form of aggregates as reinforcement in the concrete solve the problem of disposing the waste and increase the flexural strength of concrete. Different tests were conducted on the concrete with varying percentage of rubber tyre aggregates and comparing those results with normal concrete. Data presented includes workability, compressive strength, split tensile strength, flexure tensile strength and flexibility. This report describes an experimental study on mixing rubber aggregates with concrete at different mixing ratios (0, 5, 10, and 15) % by weight of coarse aggregates. The tests conducted were workability, compressive strength, split tensile strength, flexure tensile strength. Though there is decrease in compressive strength, workability, split tensile strength, flexural strength and flexibility get increased.

This paper presents a focused study on properties of porous concrete to widen its application to structural engineering. Mechanical properties like compressive strength, indirect tensile strength, flexural strength and physical properties like density, permeability and porosity are studied. To determine those parameters, twenty seven cubes, cylinders and prisms were tested. Also, three polymer impregnated porous concrete slabs were tested under pure bending moment to study the efficiency of selected resin to integrate particle of concrete to achieve a new generation in using porous concrete in structural engineering. Three different cement content specimens of porous concrete were considered, studied cement contents are 200 kg m3, 300 kg m3 and 400 kg m3. The results show that, increasing the cement content can increase the compressive strength, indirect tensile strength and flexural strength. Density of porous concrete is less than conventional concrete by 21 but permeability factor recorded higher value compared to conventional concrete by sixteen times. Increasing the cement content has no significant effect on either ultimate load or maximum deflection of polymer impregnated porous concrete slabs but the results recorded an achievement to use this concrete in structural engineering applications and give an easy way to cast special concrete like polymer concrete without special tools.

Strength characteristics of concrete containing post consumer metalized plast...eSAT Journals
Abstract This paper represents results of strength tests conducted on concrete containing flakes of waste metalized plastics. The feasibility of post consumer plastic waste (PCMPW) was determined on the bases of tests results of compressive strength and split tensile strength. Ever increasing generation of PCMPW has raised littering issues and has become one of the major sources for landfills. The objective of the test program was to check the feasibility of PCMPW as concrete constituent and possible way of mitigating the environmental impacts occurring from insufficient and unsafe management of PCMPW. The strength tests were performed with three sizes of PCMPW in flaks and fiber form. PCMPW was added in the mixes with 0%, 0.5%, 1%, 1.5% and 2% by volume of concrete mix. Test results reveled that strengths reduced with increased PCMPW flakes contents. However, up to 1% of addition of flakes the strength reduction was negligible for all flak sizes. Moreover, the PCMPW fiber with 1mmx17mm size improved the split tensile strength. Experimental results of compressive –split tensile strength were correlated by a standard analytical model and exhibited good agreement with the experimental results. Such concrete could be utilized in pavements, sub-structural components and in non-structural members. Key Words: Post consumer metalized plastic waste, Concrete, Compressive strength, Split tensile strength, Slump, Compaction factor.
An Experimental Study on Rapid Chloride Penetration Test of Self Compacting C...ijtsrd
Self compacting concrete SCC is a very fluid concrete and a homogeneous mixture that solves most of the problems related to ordinary concrete. Self Compacting Concrete gets dense and compacted due to its own self weight. An experimental investigation has been carried out to determine different characters like filling ability, passing ability, segregation resistance workability and strength of Self Compacting Concrete SCC . And finally determining the chloride penetrability of SCC. Self Compacted Concrete is generally defined as the “Concrete, which does not need Compaction.†Due to these characteristics, SCC is ideally suited for concreting structures, which have heavily congested reinforcement or difficult access conditions. In this project, M40 grade concrete were made using European method. The compressive strength, split tension test obtained at the ages of 7, 14 and 28 days. Mr. R. Jeya Prakash | Ms. R.

Experimental Study on Utilization of Hybrid Fibers in Self Compacting Concreteijtsrd
Self compacting concrete is a non segregating concrete that is placed by means of its own weight. It is highly flow able concrete that can spread without need of vibration. In this study steel and polypropylene fiber are used as hybrid fiber to enhance the workability of the concrete. In addition to this, CONPLAST SP 430 is used as a chemical admixture which is added to SCC by the volume of 2 of cement. These components like hybrid fiber and super plasticizer are added to the concrete to improve the better strength and durability of SCC. In this study, the various mix proportions of fibers discussed in this study are 0 , 0.25 , 0.5 , 0.75 , 1 , 1.5 determined by preliminary test on self compacted materials. By this desired compositions test for fresh concrete such as slump flow, L box and V funnel, U box, J ring are performed for SCC. It is found that compression and split tensile strength has been improved by the addition of hybrid fibers at 1 respectively. This experimental investigation is carried out to improve the compressive, split tensile and flexural strength in SCC for obtaining the optimum value. S. Janani | P.

Abstract
Self compacting concrete has been playing vital role in the mass concreting nowadays especially in the structures where
reinforcement used is very dense and in narrow tubular sections. This paper talks about its comparison in behavior using PPC
and OPC with different proportions of fly ash in the mix which were taken as 15%, 25%, and 35% in place of cement. For one
proportion, a set of 6 cubes was casted and the same was to be tested at 7 days and 28 days for strength. The temperature of
sample cubes was kept constant at 24°C for the whole period. The mix design was done for M25 grade. The W/C ratio was kept
constant at 0.45. The proportion of fine aggregates to coarse aggregates was kept at 70:30 and maximum size of aggregates was
20 mm. Total powder content was kept at 530 Kg/m3
. The quantity of super plasticizer was kept at 450 ml for the samples which
was 1% of the total volume. The properties were checked by conducting slump test, J-Ring Test, L-Box Test, V-funnel Test, and U-
Box Test with compressive strength test after 7 days and 28 days. The slump value was maximum for 35% replacement of cement
with fly ash and lowest for 25% replacement in PPC mix whereas in OPC mix this value increased with increasing proportion of
fly ash. V-funnel value was decreasing in both cases with increasing proportions of fly ash. J-ring value was highest for 25%
replacement in both cases. U-box value was maximum for 25% replacement in both cases and showed almost the same trend. L-
box value was lowest for 25% replacement in both cases and showed the same trend as in U-box test. The most important
compressive strength test showed very surprising results. Only 15% replacement samples showed characteristic strength after 7
and 28 days whereas 25 % replacement samples gained only 55% of desired strength and 35% replacement samples gained only
33% of desired strength after 7 days and gained 92% and 80% of desired strength after 28 days respectively in PPC samples. The
similar tests conducted on OPC samples showed the same pattern but overall strength gain was higher than PPC samples and the
margin was spectacularly high ranging between 40%-60%.

1. INTRODUCTION
Self-compacting concrete (SCC) has been described as "the
most revolutionary development in concrete construction for
several decades"(efnarc,2002). Self compacting concrete, a
recent innovation has numerous advantages over
conventional concrete. it can spread and fill all corners by
means of itself weight only, thus eliminating the need of
vibration for any type of consolidation effort[1]. originating
in Japan[2] with a view to reduce the reliance on skilled
workers and to enhance productivity of construction without
compromising quality of concrete[3]. also known as self
consolidating concrete, super workable concrete, no
vibrating concrete[4]. It is flow able and deformable without
segregation[1,4]. In order to maintain deformability along
with flow ability in paste, a super plasticizer is an
indispensable ingredient for such concrete.
SCC typically has a higher content of fine particles and
different flow properties than conventional plasticized
concrete. It should have three essential properties: filling
ability, resistance to segregation and passing ability. the
mixture proportioning is based on creating a high degree of
flow ability while maintaining a low w/c ratio. This is
achieved by using water reducing admixture combined with
stabilising agents such as viscosity modifying admixture to
ensure homogeneity of mixture for reasons of achieving
better rheological properties, reduction in cost, increase in
powder content. A high amount of mineral admixture is
typically used. Use of fly ash GGBFS, limestone powder
increases fine materials in a concrete mixture[1]
Self compacting concrete can be used in different
components of structure even combined with narrow tubular
sections. It was done by using different proportions of fly
ash at constant temperature condition to see the settling by
performing different tests on the samples first by using PPC
and then by using OPC as main pozzolanic material.
Generally PPC is an obvious choice for concrete mixes
nowadays whereas OPC is being outdated despite showing
better results because of financial aspects but selection was
to be made between the two to see its behaviour in the
manufacturing of SCC[7].
2. EXPERIMENTAL STUDY
Self compacting concrete with constant w/c ratio and
quantity of super plasticizer (1%) was prepared as per the
mix design for both the cases. The percentage of 20 mm
aggregate was 30% and that of fine aggregate was 70%. The
total powder content was kept constant equal to 530 Kg/M3

in all the trials. Thereafter, to check the effects on strength
of SCC, more percentage of fly ash mixed by replacing the
quantity of cement by15%, 25% and 35%. The w/c ratio of
0.45 was kept constant . For each concrete mix, 6 cubes of
sizes 150x150x150 mm were casted to determine the
compressive strength. After casting, the specimens were
cured in water tub for 7 days at room temperature. Three out
of them were then tested after 7 days compressive strength
of SCC and the rest were tested on 28 days. The following
tests were conducted to check the specified properties of the
concrete sample prepared.
Slump flow test: Primarily to assess filling ability, suitable
for laboratory and site use.
U-Box test: The test is used to measure the filling ability of
self compacting concrete.
L-box test: The L-box test is used to assess the passing
ability of self-compacting concrete to flow through tight
openings including spaces between reinforcing bars and
other obstructions without segregation or blocking.
V-funnel test: The V-funnel test is used to assess the
viscosity and filling ability of self-compacting concrete.
J-ring test: Primarily to assess filling ability, suitable for
laboratory and site use.
Compressive strength test: The compressive strength of
concrete was measured using AIMIL compression testing
machine with a loading capacity of 2000 KN confirming to
IS: 14858 (2000). The compressive strength test was carried
out on cubes at the 7 and 28 days.

4. RESULTS AND DISCUSSIONS:
The experimental study showed that the only
change in the mix lied with quantity of cement and
fly ash, so the results were dependent on the
compatibility of these two matters with each other.
The type of cement that was used belonged to PPC
which has some percentage of fly ash already in the
composition and OPC which has purely cement
without any addition of pozzolanic admixtures .
Any addition in fly ash content was going to result
in even higher percentage of the same actually
present in the mix.
The observations showed that the results were
always within permissible range, anytime in any
mix, the critical value was not exceeded. Though
the results of different tests on OPC and PPC
showed different trends and patterns . The results
were randomly varied for different experiments and
different proportions.
The compressive strength results of PPC sample
showed that after 7 days, the mix with least fly ash
content gained maximum strength which was
desired as per 67% of total characteristic strength.
The remaining samples gained very less strength in
first 7 days but started gaining after this time to 28
days time mainly because of secondary hydration
of lime which generally occurs in fly ash but the
overall strength gained even after 28 days was
maximum with least fly ash percentage content
than the rest. So it can be deduce that quantity of
fly ash should be kept around 15% of total powder
content in the given temperature and atmospheric
conditions at the above specified w/c ratio whereas
the compressive strength results of OPC samples
also showed that after 7 days and 28 days ,the mix
with least fly ash content gained maximum strength
but the average strength of OPC samples was much
higher than that of PPC samples in each
proportions of fly ash and the physical features of
PPC samples showed the evolvement of super-
plasticizers and moisture on samples which results
in reduction in strength whereas the samples casted
with OPC were dried and no moisture developed
over the surface of the samples and hence gave
higher strength.
