Evaluation of Strength Characteristics of Clayey Soil Using Rice Husk Ash and Calcium Chloride

A number of researchers have recently been interested in Black Cotton (BC) soil stabilization. In the past, black cotton soils were stabilized using calcium chloride (CC) and rice husk ash (RHA). The authors used both of them simultaneously in an attempt to stabilize BC soils. The current study aimed to assess the soil stabilizing efficacy of different ratios of rice husk ash and copper slag.

The authors used both of them simultaneously in an attempt to stabilize BC soils. The current study aimed to assess the soil stabilizing efficacy of different ratios of rice husk ash and copper slag. The mixed proportion of BC soils, calcium chloride, and rice husk ash were subjected to compaction tests, Atterberg’s limits, and the California Bearing Ratio (CBR). There aren’t many studies on the usage of calcium chloride and rice husk ash together for soil stabilization. There was just a slight change in the treated soil’s maximum dry density. The combinations of stabilized soil have shown good strength characteristics and can be used for low-cost construction projects like building roads and houses.
