The effect of coffee husk ash on geotechnical properties of expansive soil

Universität Rostock, 2020

Abstract: Expansive soil is one of the widespread typical problematic soils that poses several challenges for civil engineers.Expansive soils are hard and strong when they dry out; swell and soften when the moisture content increases.Particularly roads built on expansive soil are susceptible to early damage due to the swelling and shrinkage characteristics of this soil under changing moisture conditions.This study consists of experimental studies on the treatment of expansive soil using Coffee husk ash (CHA).
