1. DEVELOPMENT OF CAR PISTON MATERIAL FROM ALUMINIUM ALLOY USING COCONUT SHELL ASH AS AN ADDITIVE
ABSTRACT
This research presents the development of a piston material from aluminium alloy using coconut shell ash as an additive. Most damage pistons reported in literature are as a result mechanical fatigue due to wear and thermal fatigue. Investigations revealed that aluminium alloys...
2. STABILISATION OF TROPICAL BLACK CLAY USING CALCIUM CARBIDE RESIDUE AND COCONUT SHELL ASH AS ADMIXTURE
ABSTRACT
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 in...
