aCEMENT STABILIZATION OF EXPANSIVE SOIL: AN ADDITIVE AGAINST CONVENTION
E.Dhivya Bharathi M.Sakthi Muthu A.Santha Kumar S.Praveen ABSTRACT-Numerous man-made structures around the world have been subjected to considerable damage due to differential heave from moisture observed by expensive clay soils. Soft soils often cause difficulties in construction, operation with their low strength and low stiffness nature. However, the engineering properties of these soils can be enhanced by soil stabilization. Stabilization of soft soil is very much enhanced by admixtures like lime, cement, chemicals etc. In this study the performance of cement in its stabilization of soft soil has been evaluated and an attempt has been made to enhance its potential…show more content… Proctor (1933), are tests to determine the maximum practically- achievable density of soil and aggregates, and are frequently used in geotechnical engineering.Standard proctor test was carried for the soil using proctor mould as per IS: 2720 (part -VII) – 1980and the Dry density versus water content relationship was established for the soil.The laboratory test is performed to determine the relationship between the moisture content and dry density of a soil for a specified compaction effort. The compactive effort is the amount of mechanical energy that it is applied to the soil…show more content… The optimum cement content for stabilization is determined from control tests. The control tests are used as reference to understand the effects of additives on the stabilization potential.
VI. EXPERIMENTAL TEST VALUES
A. Effect Of Additives On Soil Properties
This section deals with the effect of stabilizers and additives on the various properties of the soil. The properties that have been analyzed for interpretation are Liquid limit, Plastic limit and unconfined compressive strength.
Effect On Liquid Limit
The variation of liquid limit with cement is shown below, The addition of cement has reduced the liquid limit thereby improving the soil.

It can be seen that addition of ceramic dust has resulted in increase in plastic limit in all cases in the
6-8% range of ceramic dust addition barring 2% cement addition trail.
