Abstract

Soil existing at a particular site may not be suitable for construction works. The purpose of this study is to investigate the utilization of Ground Granulated Blast Furnace (GGBF) Slag with lime and cement as stabilizer.Soil sample collected for this study was classified as clayey soil of low plasticity (CL).The optimum cement content has been fixed as 7% by dry weight of soil, which was replaced with GGBF as Cement:GGBF Slag ratio 7:0, 6:1, 5:2, 4:3, 3:4, 2:5,1:6 and 0:7. The optimum lime content was determined by Eades & Grim's pH method as 5% of dry soil. Lime: GGBF Slag contents 5:0, 4:1, 3:2, 2:3, 1:4 and 0:5 were used. Optimum content of GGBF Slag with Lime and Portland cement was determined based on the UCS. The results show that Cement:GGBF ratio of 3:4 gives 13.5 times higher strength than virgin soil at 28 days of curing and Lime
