Effect of Curing Methods on the Compressive Strengths of Palm Kernel Shell Concrete

Appropriate curing of concrete is necessary to obtain maximum durability and achieve designed strength for exposed different environmental conditions. Curing regarded as the means regulating degree extent loss moisture from when cement in undergoing hydration. This study made a comparative consequence adopting methods on compressive modified with Palm Kernel Shell (PKS) aggregate. Concrete cube specimens mix ratio 1:1:2 were cast water-cement 0.55. The cured using four (4) procedures: immersion, sprinkling, wet-curing open-air. samples tested their strengths at ages 7, 14, 21 28 days curing. results obtained show that immersion method has highest value 17.07 N/mm2. was followed by sprinkling 15.78 Wet-curing 14.48 N/mm2 open-air 13.11 It concluded are suitable PKS concrete.
