Influence of Pond Ash on Compaction and Strength of Clayey Soil Mixed with Terrazyme

Abstract

AbstractIt is an incredibly challenging task to construct structures over the soils possessing poor geotechnical characteristics. The present study is focused on improving the geotechnical properties of clayey soil using pond ash and terrazyme to use it as a subgrade material. Various percentages of both the materials, i.e., pond ash varying from 10 to 30% and terrazyme varying from 0.04 to 0.12 ml/kg have been used to perform Atterberg’s limits, compaction, and California bearing ratio tests. It was revealed that the addition of pond ash to clayey soil reduced liquid limit. The addition of 20% pond ash along with 0.08 ml/kg terrazyme gave maximum dry density. The California bearing ratio value was enhanced by the addition of optimal quantity of both the materials to clayey soil. This confirms that the mixture of 20% pond ash along with 0.08 ml/kg terrazyme to stabilize poor soils is economical and environmental.KeywordsSoil stabilizationPond ashTerrazymeConsistency limitsCompactionCalifornia bearing ratio
