ABSTRACT
In this study the bearing capacity of granular soil was improved in order to reduce settlement and this was done by grouting. The structures constructed in the coastal belt often require deep foundation due to the existence of weak soil which has poor Engineering properties. The soil profile about 3 to 4 meters deep, in these areas is mostly loose sand which is then underlain by clayey soil. The structures constructed here suffer shear failure and excessive settlement due to low bearing capacity. Ordinary Portland cement was used as grout material as it is readily available and cost effective. Different tests were carried out on the sample to determine the index properties of the soil. Some of which include particle size distribution tests, Atterberg limit tests, specific gravity test, CBR test and compaction tests. It was found that shear strength of the grouted sand increases with the increase in cement quantity. It was deduced from results that 4% cement grout is effective as compared to 2% and 6% of grout.
