Study of Stabilization of Soil with Stone dust, Fly Ash and Coir Fiber
Keywords:
Soil, Coir Fibre, Stone Dust, Fly Ash, Soil Stabilization, CBRAbstract
In this paper, the individual as well as combined use of stone dust, fly ash and coir fibre in the soil stabilisation is investigated. Fly ash and stone dust was nixed in the soil at individual percentage varying from 5% to 20% and coir fibre was mixed with percentage varying from 0.5% to 2%. Five different samples of each replacement were made at different percentages based on the individual results the five different samples with combination of stone dust, fly ash and coir fibre was made and tested for optimum moisture content, maximum dry density, california bearing ratio and unconfined compressive strength. The values of all testes performed by mixing soil withstone dust, fly ash and coir fibre was then compared with soil sample and it was found that mix of soil with up to coir fibre 2%, fly ash 15% and stone dust 20% gives maximum value of dry density, soil mix with coir fibre 1%, fly ash 20% and stone dust 20% has given maximum cbr value 24.52 and maximum ucs value 168.59 was found with mixture of soil with coir fibre 2%, fly ash 15% and stone dust 20%.
