Improving Engineering Properties of Clayey Soil with Addition of Cement and Coir Fiber
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 9
Abstract
In recent days, improving engineering properties of soil with various waste product such as(hair fiber, coir fiber) etc. We found that these by-products can improve and maintain the properties of soil. Soil reinforcement is most effective technique for improving soil strength. Clay is introduced for their high compressibility and poor shearing strength, it create various problems for builders. During this work the effect of moisture content, degree of compaction, synthetic fiber as a reinforcement etc. on various Geotechnical properties of cement and coir fiber are studied. A many different tests (Tri-axial, Unconfined Compression, CBR, Direct shear test) were conducted on this subject by several investigators. Here we use locally clayey soil reinforced with random distribution of coir fibers at different percentages. The bearing capacity of soil with three different proportion (0.25%, 0.5% and 0.75%) of coir fiber and two cement (3%, 6%) proportion is using for the testing of bearing capacity or settlement of clayey soil reinforced with randomly fiber. The objective of this investigation is found the optimum quantity of randomly distributed fibers & cement on the performance in term of strength of soil. It was found that fiber & cement content had significant influence on the engineering properties of fiber-cement treated soil. In this investigation, it was also found that with an increase in fiber content caused an increase both ductility & strength. The coir reinforced layer improves the bearing capacity of clayey soil and it is economical method for various types of bearing capacity improvement techniques.
