Stabilization of Clay Soil Using Lime and Polypropylene Fibre

Abstract

Abstract: Soil is the basic foundation for any civil engineering structures. It is required to bear the loads without failure. In some places, soil may be weak which cannot resist the oncoming loads. In such cases, soil stabilization is needed. Numerous methods are available in literature for soil stabilization. But sometimes, some of the methods like chemical stabilization etc. adversely affect the chemical composition of the soil. The following material were used for preparing the samples; Clay soil Lime Polypropylene fibre (12mm length) Clay soil used for these experiments was brought from site, near EB Office, Kadayanallur. The physical properties of soil were determined as per IS specifications. This project aims to conduct a study to check the improvements in properties of clayey soil by adding lime (constant 3% weight of the clay soil) and various percentage of Polypropylene fibre (0%,0.25%, 0.50%, 0.75%, and 1.0% weight of the clay soil). These mixtures were investigated by conducting standard proctor compaction test, unconfined compression test and CBR test. The test were performed as per Indian standard specifications. Finally the maximum strength is obtained at 0.50% PPF and by maintaining 3% lime.
