STRENGTH BEHAVIOUR OF MARINE CLAY TREATED WITH RICE HUSK ASH

The amount of wastes has increased year by year and the disposal becomes a serious problem. This paper presents the effects of rice husk ash on, liquid limit, plastic limit, compaction characteristics and California Bearing Ratio on marine clay soil. The marine clay collected from Kakinada, East Godavari Dt, Andhra Pradesh was mixed with rice husk ash waste from 0 to 25% at an increment of 5%. From the analysis of test results it was found that, specific gravity decreases, liquid limit, plastic limit, optimum moisture content, maximum dry density and California bearing ratio are increased with an increase in RHA up to 20% addition beyond it is not m uch effective.
