Stabilization of Subgrade Black Cotton Soil using Quarry Dust and Foundry Sand

Abstract

Soilsstabilization cansbesexplained as the alteration of the soilsproperties by chemical or physicalsmeans in order to improve thesengineering excellence of the soil. The main objective of the soil stabilization is to raise the bearingscapacity of the clay soil, its opposition to weathering method and soilspermeability. The long-termsperformance of any constructionsproject depends on the reliability of the underlying soils. unsound clay soils can create considerable problems forspavements, Thereforessoil stabilization techniquessare essential to ensure the good constancy of clay soil so that it can successfully uphold the loadsof the superstructure specially in case of clayssoil which are very active, alsosit saves a lot of time andsmillions of funds whenscompared to the technique of cutting out and replacingsthe unsound soil. In this Studysdeals with the entire analysis of the enhancement of black cotton soilsproperties and itssstabilization using Quarry Dust and industrial Foundry sand. The basic tests were carriedsout on soil, quarry dust and foundry sand are Atterberg’s Limit, Modified Proctor Compaction and CBR Test with addition of 5%, 10% and 15 % of Quarry Dust to soil sample after result analysis, obtained keeping Quarry Dust 15% constant and addition of Foundry sand 5%, 10%, 15% and 20%. After test results the maximum CBR Value found at 15% Quarry Dust and 15% Foundry Sand. Dumping of these waste materials is necessary as these are causing dangerous effects on the surroundings. With the same purpose literature review is undertaken on consumption of solid desecrate materials for the stabilization of soils and their performance are discussed.
