Abstract

The grouting is one of most important Ground improvement technique which is used to improve strength of soil especially sandy soils by introducing Cohesion in the soil. Sandy soils have weak Bearing strength due to absence of Cohesion in the soil. In this technique, the grout is introduced in the Voids of the soil. In this paper, we will try to compare the Bearing strength of the soil by adding 2%, 4%, 6% cement content. The Bearing strength of the soil is generally assessed with the Plate Load Test (sometimes Direct Shear Test and Unconfined Compression Test can also be used) and in this we have compared the strength of soil without grouting and after pumping grout in the sandy soil. And we found that 4% cement grout is more effective than 2% and 6%. The researcher made a specimen of sandy soil grouted with cement slurry and kept under Curing for 28 days and then test is taken. The effectiveness of grouting process requires proper skills, understanding, meticulous attention and intuitive perception. So, in this paper, we will compare results obtained from various Research papers so that Grouting techniques can be implemented based on standard design principles and well defined procedures instead of using general thumb rules and basic traditional practices. We will also study the efficiency of grouting technique as compared to compaction method.
