Numerous materials have been proposed and developed in recent years to improve the swelling features of expansive soil under moisture conditions while minimizing economic costs and environmental impact. This research deals with the improvement of expansive properties of clay soils by chemical treatment using biomass sludge as a product from the last operating stages of wastewater treatment plants used to stabilize the expansive soil. Experimental tests are carried out on treated expansive soils with sludge to exam the swelling characteristics of the expansive soil. In these experiments, three different percentages of the treated biomass sludge by dry weight of soil (3%, 5%, and 7%) were added to the expansive soil to evaluate the efficiency of using the treated material. The results of the present investigation show that the use of sludge efficiently improves the swelling characteristics. Furthermore, the optimum percentage of the treated biomass sludge was 7%, which reduced the swelling pressure by around 36% in comparison with untreated soil. [ABSTRACT FROM AUTHOR] |
