A Study on Swelling Characteristics of Black Cotton Soil by Using Sugarcane Baggage Ash and Phosphogypsum

In developing countries like India, due to remarkable development in road infrastructure , soil
stabilization has become major issue in constructional activity, stabilization is not only a method of
altering or modifying of one or more soil properties to improve the engineering . Characteristics and
performance of a soil ,but also processing available materials for the production of low –cost design
and construction
Black cotton soils which expand when moisture content of soils is increased the clay mineral
montmorillonite is main responsible for expansive characteristics of soil. the expansive soils called
swelling of soils or black cotton soils a large part of south India is covered with expansive soil
another problem with this soil is strength is decreases with increases of degree of saturation heavy
damages may occur buildings roads runways pipe lines and other structures built on such soils if
proper preventive measures are not method. The damages can be prevented to an large extent if
characteristics of expansive soil properly assessed suitable measures taken in design construction and
maintenance of structures built on soils. This presents experimental investigation to study the effect of
sugarcane baggage ash & phosphogypsum on swelling and shrinkage and mechanical properties of a soil.
After finding out the experimental results in lab to know the evaluation and performance of baggage ash on
the black cotton soil in the laboratory
Black cotton soil and baggage ash & phosphogypsum mixture has prepared by varying of
different proportions with respect to dry the density
