Experimental studies on hydraulic conductivity of different straw fiber cement treated mud

Abstract

Hydraulic conductivity characteristics of mud treated by rice straw fiber and cement were investigated by falling head permeability tests. The experimental results indicated that the water conductivity significantly decreased by the inserting of either cement or rice straw fiber. Comparing with cement-treated mud, the addition of rice straw fiber considerably reduced the water conductivity of the mud composite. Moreover, empirical equations were revealed to predict the value of hydraulic conductivity for the modified-mud.
