SOIL STABILIZATION OF BLACK COTTON SOIL BY USING FLYASH AND COCONUT FIBER

The soil is very important in the civil engineering constructions. The poor engineering properties of the local soil may cause difficulties in a construction. The black cotton soil is an expansive soil, which can be seen in various locations of India, and also extensively distributed mostly in South India. The black cotton soils are the major source of great damage to infrastructure, buildings and roads also. The black cotton soil changes according to the seasonal variations of the climate in that area. When it is rainy season, the soil absorbs the water and swell, and when it comes to summer season the soil will be affected to shrinkage. Due to these changes the super structures like buildings and pavements, foundations got severely damaged. The fly ash is a by-product of the coal and is obtained from thermal power stations. Soil stabilization of black cotton soil by using fly ash and coconut fiber. In this project we are stabilizing the black and the usage of coconut fiber is very high and the displacing of these materials is the major problem due to its non disposable characteristics.
