Effect of Rice Husk Ash (RHA) as a Pozzolan on the Strength Improvement of Cement Stabilized Peat

Cement is one of the most effective conventional methods for peat soil stabilization. However, this method is not environmentally friendly because the use of too much cement causes much carbon dioxide to be produced for cement production. Rice husk ash (RHA) is applied as substitution for Ordinary...
