A Review on The Lime and Fly ash Application in Soil Stabilization

Abstract

Nowadays, inefficient properties of soils are a critical issue in engineering projects. In some cases, improve the characteristic of unsuitable soils is a fundamental step for making construction. This review paper presents the results of research on soil stabilization with lime and fly ash. Soil stabilization performed the use of technique to adding a binder to the soil in order to improve the engineering performance of soil. Researches were illustrated that adding the additives leads to progress in workability and mechanical behaviour of soil after stabilization. Lime and fly ash as local natural and industrial resources were applied for chemical stabilization. These additives could improve the mechanical properties of soil such as strength, swelling, plasticity index and compressibility. The obtained results were indicated that, for progressing in soil properties the combination of lime and fly ash might be more effective than use of only lime or fly ash.
