The document discusses the stabilization of black cotton soil using wooden ash. Black cotton soil has low strength and undergoes excessive volume changes, making it difficult to use for construction. The study aims to evaluate using wooden ash to increase the compressive strength of black cotton soil. Various laboratory tests were conducted on samples of black cotton soil with different percentages of added wooden ash, including specific gravity, particle size distribution, liquid limit, and standard proctor compaction tests. The results showed that adding 2-12% wooden ash to black cotton soil at the optimum moisture content increased the soil's strength and reduced changes in volume, showing potential for economic use in construction applications.
Overview of Soil Stabilization :Cement / Lime :PPTAniket Pateriya
Soil-cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a sub-base layer reinforcing and protecting the subgrade. It has good compressive and shear strength, but is brittle and has low tensile strength, so it is prone to forming cracks.
Lime can be used to treat soils to varying degrees, depending upon the objective. The least amount of treatment is used to dry and temporarily modify soils. Such treatment produces a working platform for construction or temporary roads. A greater degree of treatment supported by testing, design, and proper construction techniques--produces permanent structural stabilization of soils.

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.

An Experimental Study on Stabilisation of Loose Soil by Using Sisal Fiberijtsrd
Soil Properties which creates a crucial impact on construction activities due to the rapid growth of urbanization and industrialization. Especially in expansive soils are creating worldwide problematic soil these having large volumetric change behavior when it undergoes a change in the moisture content. Among those, black cotton soil are one type of expansive soils and they show high swelling and shrinkage behavior owing to fluctuating water content. In India, black cotton soil covers as high as 20 of the total land area and majorly in central and south India. If it should be used as foundation material, Improvement of soil need to be done by adopting various techniques like soil stabilization, reinforcement etc. Usage of locally available admixtures is effective in terms of easy adaptability and economy.The main objective of this study is to assess the possibility of using sisal fiber as a stabilizing agent and to understand the effectiveness of sisal fibers in controlling several properties of black cotton soil under controlled laboratory conditions. To achieve this goal several experimental studies like optimum moisture content, compressive strengths tests UCS , CBR, etc., were carried out with the addition of different percentages of sisal in black cotton soil sample as trial and error process. In the present study, the soil samples prepared with the addition of sisal fibers by 0.25 , 0.5 , 0.75 , and 1 the average length of sisal fiber is going to use in this study is approximately 10 15mm. At first, Optimum Moisture Content OMC was determined through the proctor test. At those OMC, several tests like CBR, UCS were conducted. CBR test was carried in both Unsoaked and soaked condition and maximum values were obtained where 0.75 sisal fiber was added. K. Rupa Narayana Reddy | P.

Cement is a major construction material worldwide. However, given the escalating costs of cement and the environmental hazards associated with the use of cement there is need to develop alternative, costeffective, non-conventional, locally available materials, especially those that can partially or wholly replace cement. This paper presents the results on the study of the effect of local brewery waste and bitter cassava flour on the compressive strength and shrinkage of plaster. The test was made with cement replaced by local brewery waste or bitter cassava (10-50%) and cement/sand mix as a control. The results showed an optimum of 20% cement replacement with bitter cassava for plaster mortar for high cost houses (18.1Mpa) and 10% cement replacement with local brewery waste for plaster mortar for low cost houses (2.1Mpa). Result show a maximum shrinkage of 8mm at 50% replacement with bitter cassava and zero shrinkage for 50% replacement with local brewery waste. Furthermore only the control, 40% and 50% with bitter cassava flour showed cracks of about 2mm for mix ratio 1:3 and 1:4.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. Introduction
Aimed at evaluating the possibility of utilizing
wooden ash in the stabilization of black cotton
soils
Black cotton soils possess low strength and
undergo excessive volume changes, making their
use in constructions very difficult
These soils cause more extensive damage than
even natural disasters
Hence, we must increase the compressive
strength of black cotton soil with using of
wooden ash
3. Reasons for this Study
Economic progress and growth of a country is closely
dependent on the infrastructural development
Pavements of least thickness are found to be the most
economical
This is possible only when the underlying soil has
greater strength
Black cotton soil possesses low strength. If the soil is
weak, then the thickness of the pavements increases.
So for such problematic soil, it is essential to stabilize
them in the most economic and affective way.
4. Feasibility of Wooden Ash
Various research works have been undertaken for
improving the expansive nature of the black cotton
soil using materials like wooden ash, as admixture.
Wooden ash is a locally available material residue
powder left after the combustion of wood, such as
burning wooden in a home fireplace or an industrial
power plant.
It is used traditionally by gardeners as a good source
of potash for domestic gardens.
5. Material Source
Black cotton soil has been collected from a
field in Athupalam, Coimbatore
Wooden ash has been collected from
Malumichapetti region.
6. Laboratory tests
The following are the various laboratory tests
conducted on the samples collected
Specific Gravity test
Dry Sieve Analysis
Relative Density Test
Liquid Limit Test
Plastic Limit Test
Standard proctor compaction Test
7. Natural Moisture Content
NATURAL MOISTURE CONTENT
All moisture content determination was done by the oven
drying method
For the determination of natural moisture content, samples
were collected in polythene bag and immediately taken to the
laboratory for the test.
The water content is calculated from equation.
8. Where m1 = mass of container (g)
m2 = mass of container and wet soil
(g)
m3 = mass of container and dry soil
(g)
The natural moisture content was determined
to be 26.95 %
9. Specific Gravity
The density bottle method The specific gravity
of the soil sample was done by using density
bottle method.
The sieved sample was grouped into
approximately four equal parts.
Each part was placed into dried 50cm3 density
bottle of known mass (M1) to the nearest
0.01gsing
10. The mass of each bottle with sample inside
was measured (M2) to the nearest 0.01g.
Each bottle was then filled with water and
mixed thoroughly removing all air bubbles.
The bottle was weighed to a mass (M3).
11. Finally each bottle was washed and dried.
Water was introduced and the mass of the
bottle with water full taken (M4).
The specific gravity is expressed as :
Gs = =2.941
The average of the values was taken for
various samples.
13. Particle Size Distribution
The particle size distribution of the natural
soil was determined using the method specify
by BS 1377 (1990) for cohesive soil.
It specifies the use of both sedimentation
analysis and the dry sieving of the coarse
fraction
14. When the black cotton soil was treated with
2 - 12% wood ash by dry weight of soil at
optimum moisture content (OMC), less than
10% of the material passed through BS No.
200 sieve, and therefore did not meet the
minimum requirement for sedimentation
analysis to be carried out.
16. Liquid Limit
200g of the air dried BC soil passing 425–μm sieve size
was taken and was mixed with water and kneaded for
achieving uniformity.
The mixing time was specified as 5 to 10 min. The soil
paste was placed in the liquid limit cup, and leveled off
with the help of the spatula.
A clean and sharp groove was cut in the middle by
means of a grooving tool.
The crank was rotated at about 2 revolutions per second
and the number of blows required to make the halves of
the soil pat separated by the groove meet for a length of
about 12 mm was counted.
17. Conclusion
• From this project we observed that when
admixture is added to black cotton soil
(wooden ash) there is a increase in strength of
soil and less change in volume of soil.
• Hence its can be used economical in
construction.
