Stabilization of Problematic Soil Using RHA Cement Sisal Fiber Mixes and Analysis of Durability Effect of Sisal Fiber Using Soft Computing Technique

Abstract

Land available for construction of pavements and building are not fit or even newlinenot good in all cases. The soil shows problem while construction of structures. newlineSometimes shows problem after construction of structure during its service span newlinethose soils are considered as problematic soil. In our research we identified Black newlineCotton Soil (BC) and Litomergic Soil (LM) as problematic soil which offers less newlinestrength and more vulnerable while construction of structure on those soil. newlineHence strengthening of pavement on weak base / sub base and soil under newlinefoundation with a stabilized material are consider as an important task. newlineThe chemical stabilization of weak expansive BC soil and dispersive LM soil is newlinecommon. Geo reinforcement method of stabilization is also one of the effective newlinemethods to strengthen weak soil. The research work examines combination of newlineboth chemical and geo reinforcement method of stabilization on BC as well as LM newlinesoils with the use of Rice Husk Ash (RHA), Cement and sisal fiber. The major newlineadvantage of using RHA and cement in soil stabilization is its insensitiveness to newlinemoisture variation, high pozzolanic nature, and advantage of using sisal fiber in newlinesoil stabilization is low specific gravity, high tensile strength. The characteristic of newlineRHA, cement and sisal fiber result in significant geotechnical engineering newlinebenefits. Use of agricultural and industrial waste like RHA and sisal fiber newlineefficiently in soil stabilization may reduce effect of disposal and associated newlineenvironmental problems. newlineThe finding of the work reported on factors influencing the strength property newlineof BC soil and LM soil stabilized with the use of RHA. Cement and sisal fiber are newlineinconclusive due to the fact that the degradation of sisal fiber greatly affects newlinestrength and durability of stabilized soil. Therefore the aim of the present newlineinvestigation is to study the properties of BC soil and LM soil stabilized with the newlineuse of RHA, cement and sisal fiber / degraded sisal fiber. And to evaluate the newlineeffect of percentage d
