Mechanical Behavior Of Sugar On Palm Kernel Shell Concrete

Palm kernel shell (PKS) is an agricultural waste product that is gotten when palm oil is removed from palm oil fruit. For environmental sustainability, it may be used as coarse aggregate for production of lightweight concrete. This study investigates the effect of sugar as admixture on palm kernel shell concrete (PKSC) made with 30% palm kernel shell replacement of coarse aggregate. Concrete mix proportion adopted in the research was 1:2:4 and water-cement ratio of 0.5. Sugar of 0.00%, 0.03%, 0.05% and 0.10% by cement volume was used respectively as concrete admixture. The tests carried out on the produced concrete were workability, density and compressive strength using relevant standard at the curing ages of 7, 14, and 28days respectively. The test result revealed that, as the sugar admixture increases, concrete workability also increases while the result of both density and compression strength keeps reducing.
