An Experimental Study on Stabilization of Expansive Soil by Copper Slag

Abstract

Abstract: Stability of any structure depends on strength properties of underground soil on which it is constructed. Structures basically transfer all the loads come on itself directly to the ground. If the underlying soil is not stable enough to support transferred loads then various types of failure occur such as settlement of the structure, cracks and so on. To solve this issue, soil improvement is necessary because it not only lowers the construction cost but also cuts the risk of any damage of structure later on. Numerous improvement methods can be adopted to make ordinary soil stable enough to support the structural loads. In this research work a number of tests may conduct using both ordinary soil and stabilised soil. The stabilising agents are using in this study is Copper Powder. The varying percentage of 5%, 10%, 15%, 20% and 25% added to the expansive soil. It binds the soil particles together and helps in reduction of rapid change in volumetric properties. The tests may conduct on un-stabilised and stabilised expansive soil is CBR, UCS and tri-axial test.The test may conducted on untreated and treated expansive soil i.e. index properties (liquid limit, plastic limit), compaction test, California bearing ratio (CBR), unconfined compressive test (UCS), Triaxial test
