Influence of Crumb Rubber and Polypropylene Fibre on the Behaviour of Cemented Black Cotton Soil

The research was being carried out all over the world on expansive soils to mitigate their problematic behaviour and suggested various ground improvement techniques, in recent times, among which chemical stabilization is quite popular. In this stabilization process, the soil is mixed with cement, lime and several industrial reactive by-products such as fly ash, bagasse ash, etc., have been used for stabilization of soil in weak deposits. Even unreactive by-products like crumb rubber and polypropylene that are produced from scrap tyre and polymers, respectively, are also being utilized that reduces the burden on landfills. In this study, crumb rubber and polypropylene were used to assess the modification in geotechnical properties of a lime cemented black cotton soil. The geotechnical properties of virgin soil were determined and a lime content of 4% was fixed for carrying out subsequent experiments based on the pH test and the Atterberg limits. A 0.25% polypropylene content and varied crumb rubber contents of 0, 1, 2, 5 and 10% were added to the lime cemented soil in order to find the optimum dosage using the unconfined compressive strength (UCS) testing. Based on the test results, 5% crumb rubber was found to be the optimum content that could be effectively used to improve the strength.
