This research paper presents the relation between the strength and soaking period. Soaking period had a considerable effect on strength of the soil mixture.In this we used rice husk ash and stone dust as additives as they were economical. For the present work effect of soaking on the additives was studied extensively. Rice husk ash and stone dust are added to the soil with varying their content from 2% to 12% at optimum content of lime 8%. Samples were prepared for unconfined compression test and these samples were tested at different soaking periods. (i.e. 7, 14, 28, 56 days of soaking).The results showed that there was a considerable increase in strength from 7 days to 28 days soaking as lime reacts it is expected to reach maximum at 28 days, from then till 56 days increase the strength of the soil is comparatively very less compared with increase in strength for 28 days soaking.
