63. STABILISATION OF TROPICAL BLACK CLAY USING CALCIUM CARBIDE RESIDUE AND COCONUT SHELL ASH AS ADMIXTURE
A Tropical Black Clay (TBC), obtained by method of disturbed sampling, at a depth of between 0.5m to 1.5m, at Gwako village, Abuja, Nigeria, was treated with 0, 2, 4, 6, 8, and 10% each of Calcium Carbide Residue (CCR) and Coconut Shell Ash (CSA). Effect of the additives was investigated with respect to compaction characteristics (Maximum Dry Density-MDD and Optimum Moisture Content-OMC) and Unconfined Compressive Strength (UCS) cured at 1, 7, 14, 28, 60 and 90 days.
