Effects of Basalt Fiber and Coir Pith on Geotechnical Properties of Clayey Soil

Clay is a soft soil with low shear strength and high compressibility. These types of soils can be treated by stabilization. In this paper, the effects of basalt chopped fiber with coir pith on geotechnical properties of clayey soil in varying proportions are discussed. The utilisation of waste material and natural fibers helps to boost soil quality is beneficial, because they are inexpensive, accessible locally and ecological. Basalt fiber is a non - metal inorganic fiber which acts as a reinforcement for soil. It has excellent thermal, chemical, mechanical properties and environmental friendly material. The stabilizing effect of both the fibers on soil properties was observed. Addition of fibers improved the soil properties such as shear strength, and showed significant effects on cohesion, shrinkage characters. Also, it reduces desiccation and cracking.
