Variables Controlling for Atterberg Limits of Kota Stone Slurry Dust Stabilized Expansive Soil

Abstract

The production rate of industrialization increases the demand for waste disposal. The method of disposing waste in soil is one of the conventional methods which require a large area of land, but now due to the lack of availability of land, this waste is used as a soil stabilizer in the technique of soil stabilization. From the civil engineering point of view, the kota stone dust, marble dust, rice husk, fly ash, blast furnace slag, foundry sand, glass waste, tiles waste, ceramics waste etc. are the commonly waste which are used as a construction materials with replacement of conventional materials successfully and also having effective characteristics required by a good soil stabilization admixture. In this paper, the reduction of this problematic nature of soil by blending of stone quarry waste material such as kota stone slurry has been attempted. A number of Consistency Limits (Liquid Limit, Plastic Limit and Plasticity Index) tests are carried out on Expansive soil (Black Cotton Soil) stabilized with various kota stone slurry (KSS) contents. The results show that Consistency limits (CL) fitting curves were followed liner pattern with the increase in KSS and a linear line function has been fitted to assess the optimum relationship between CL and KSS percentage. It is observed that for the relationship among CL and KSS, the optimum fit could be obtained after applying the slope equal to -0.4 to the KSS content (L) parameter. Finally, a unique relationship between CL and KSS is also established, i.e., CL = 86.53-18.64x-0.4k, where k and x represents KSS contents and various consistency limits.
