An Experimental Study on Stabilisation of Loose Soil by Using Sisal Fiber

Soil Properties which creates a crucial impact on construction activities due to the rapid growth of urbanization and industrialization. Especially in expansive soils are creating worldwide problematic soil these having large volumetric change behavior when it undergoes a change in the moisture content. Among those, black cotton soil are one type of expansive soils and they show high swelling and shrinkage behavior owing to fluctuating water content. In India, black cotton soil covers as high as 20 of the total land area and majorly in central and south India. If it should be used as foundation material, Improvement of soil need to be done by adopting various techniques like soil stabilization, reinforcement etc. Usage of locally available admixtures is effective in terms of easy adaptability and economy.The main objective of this study is to assess the possibility of using sisal fiber as a stabilizing agent and to understand the effectiveness of sisal fibers in controlling several properties of black cotton soil under controlled laboratory conditions. To achieve this goal several experimental studies like optimum moisture content, compressive strengths tests UCS , CBR, etc., were carried out with the addition of different percentages of sisal in black cotton soil sample as trial and error process. In the present study, the soil samples prepared with the addition of sisal fibers by 0.25 , 0.5 , 0.75 , and 1 the average length of sisal fiber is going to use in this study is approximately 10 15mm. At first, Optimum Moisture Content OMC was determined through the proctor test. At those OMC, several tests like CBR, UCS were conducted. CBR test was carried in both Unsoaked and soaked condition and maximum values were obtained where 0.75 sisal fiber was added. K. Rupa Narayana Reddy | P.
