Abstract
Utilization of industrial by-products such as ground granulated blast furnace slag and metakaolin in the ground enhancement and soil stabilization causes the economic and environmental benefits. Ground granulated blast furnace slag (GGBFS) is a by-product of metal industry. Metakaolin (MK) is produced during the de-hydroxylation kaolinitic clay and pozzolanic in nature. The aim of the present study is to evaluate the effectiveness of GGBFS and Metakaolin on engineering properties of the soil. Keeping in view, the experiments are performed at various dosages of GGBFS (5, 10, 15, 20 and 25%) and MK (5, 6, 7, 8, 9 and 10%) to stabilize the soil and evaluate index properties, compaction characteristics and strength of these soils as per Indian standards. The investigation reveals that collective use of both ground granulated blast furnace slag and metakaolin form a binder which offers new prospects to boost pozzolanic actions that will enhance the geotechnical properties of the soil.
