Abstract: This paper presents the effect of RBI GRADE 81, LIME & CERAMIC DUST. The various properties of soil like liquid limit, plastic limit, unconfined compressive strength, compaction characteristics, California bearing ratio and swelling pressure of an expansive soil. Black cotton soil collected locally was blended with different percentage of stabilizer according to the previous research which is conducted on individual stabilizer. From the analysis of test result, it was observed that plastic limit, liquid limit, plasticity index, swelling pressure and optimum moisture content of soil decreases. Maximum dry density, unconfined compressive strength and California bearing ratio increased with the percentage increase of stabilizer (lime, ceramic dust, RBI grade 81). As an effective analysis It was founded that on comparison of above three stabilizer RBI grade 81 gives better result between 3% to 6% addition to the soil can be used in enhancement of soil properties. Keywords: Black Cotton soil, RBI grade 81, lime, ceramic dust, CBR value, compaction value, UCS.
I. INTRODUCTION
In the dense population country like India 1.38 billion (approx.). At an area of 32,85,239 sq.km. less land remains or construction due to increase of urbanisation. Land is used for different purpose and structure from a simple building to skyscraper, flyover to airport and from rural road to expressway. Soil is cheap and easily transportable construction material in the field of civil engineering. But due to its poor properties in the field of engineering it’s needs to be stabilized by different method of stabilization. Low properties of soil provide insufficient strength to bear the load imposed on its at its useful life. Availability of soil at different places have varies its properties which required to be stabilized according to type of construction. Recently new techniques are developed to stabilised the soil, new polymer stabilizer RBI GRADE-81 , CERAMIC DUST and LIME is an innovative material product to stabilized the soil these are environment friendly powder based stabilizer & increases the property of soil at the optimum level ,different techniques improve the properties of soil but shows the variation at different percentage when added in soil. Main concert in the stabilization is greater stability with less cost of material. And material is ecofriendly and durable.
II. PROBLEM STATEMENT
All the above mention detail about black cotton soil we can conclude that soil need to be stabilised for used in any type of construction. Improvement in the properties of soil can be done by any of waste material there on the basis of usability & transportability of waste material. By use of different waste material different changes in properties of soil may observed. Soil stabilization become necessary & should be tested in the laboratory. before get applied on the field. There is attempt done to improve the properties of soil by means of ceramic dust, lime & RBI Grade 81 their result gets compared which give idea about economical & efficient mode to stabilized the soil.
III. OBJECTIVEOFTHESTUDY
A. To study the effect of different percentages of ceramic dust, lime & RBI GRADE 81 on Atterberg’s limits (Liquid limit, Plastic limit) and Differential free swell (DFS). B. To study the effect of varying percentages of ceramic dust, lime and RBI GRADE 81 on Compaction characteristics (OMC &
MDD), Unconfined compressive strength (UCS) and California bearing ratio (CBR). C. To compare an optimum percentage of ceramic dust, lime & RBI GRADE 81 that can be used with B.C SOIL. D. Defining the range of different properties of soil on the basis of above comparative work.
