Abstract

Black cotton soils are very expansive in nature. It is well known that they exhibit swelling nature when water is being dried out. These soils possess several foundation and stability problems of Civil Engineering structures constructed over them. Hence there is a need to stabilize the expansive soil. From the literature it was observed that chemical stabilization is very effective in stabilizing the expansive soils and has several advantages when compared to other Stabilizing methods.

In this paper the authors concentrated on the impact of calcium chloride on the strength properties of the black cotton soil. This research discusses the effects of calcium chloride on the strength of black cotton soil. The soil used belongs to the “CH” group according to IS soil classification, and its DFSI is 115%, indicating a high degree of expansive nature. It was discovered that the strength of the treated soil increases with curing time while decreasing as the pore fluid content moves from the dry side of the optimum moisture content to the wet side of the optimum moisture content, regardless of the calcium chloride percentage concentration. After extensive laboratory research it was reported that stabilization of Black cotton soil with calcium chloride improves the strength characteristics.
