ABSTRACT
The aim of this study is to demonstrate the utilization of sodium bentonite as a pozzolanic additive to reduce the permeability rate of stabilized clay. Sodium bentonite is identified as a natural pozzolan that can utilize to reduce the coefficient of permeability of cemented soil due to its fineness and high content of silica and alumina. Sodium bentonite wherein mixes with cement paste in an appropriate dosage, it is capable to impart pozzolanic effect; hence, reduce the coefficient of permeability of cemented soil. Other than sodium bentonite, ordinary Portland cement and silica sand were also used as the binder and particle size modifier respectively. For this purpose, soil specimens of both plain and treated clay were explored in laboratory. It was revealed that addition of 15% sodium bentonite reduced 2.11 times of coefficient of permeability.
