Description
Today, India is running on the way of development, thus the rapid growth of industrialization is increasing which creates scarcity of land for disposal of their industrial wastes. Hence, the urgent demand for utilization of such types of waste is coming out. 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. The current research shows the effective utilization of kota stone dust in the improvement of sub grade characteristics of black cotton soil. A number of tests were conducted in laboratory which shows that the kota stone slurry dust is a good alternative for the improvement of sub grade characteristics of black cotton soil. The Standard compaction test were conducted in laboratory for obtaining the maximum dry density (MDD) and optimum water content (OMC) corresponding to 3% to 24% of kota stone slurry dust mixed with black cotton soil in the variation of 3% each. After the determination of OMC and MDD of different proportion, the laboratory California bearing ratio (CBR) tests were conducted with the above proportion of kota stone slurry dust and it was concluded that soaked CBR value of black cotton soil blended with 18% kota stone dust increased from 2.12 to 8.37 i.e. 295%.
