USE OF SEWAGE SLUDGE ASH IN SOIL IMPROVEMENT

Abstract

The Sewage sludge ash (SSA) was added to the clay with the mixture ratio of 0% 10%, 20%, 30%. The SSA used in the research is a product generated during the combustion of sewage sludge in Gaziantep municipal wastewater treatment plant. The clay employed in the experimental studies was obtained from the Gaziantep University of Gaziantep campus. An intensive series of fall cone tests (FCT) were performed on the clay-SSA mixtures. The results indicated that the liquid limit estimates and undrained shear strength values of the mixtures were increased by the addition of SSA contents

Keywords
