Abstract

Various methods of curing for usually adopted to evaluate the compressive strength of concrete Normal concrete was prepared with a water-cement ratio of 0.40. Cube specimens were cast for testing the compressive strength at 7 ,14 and 21, 28 days of curing respectively using five curing methods namely covering concrete surfaces with hessian or gunny bags, sprinkling of water, Ponding method, Membrane curing, Steam curing and Covering concrete surfaces with hessian or gunny bags, curing to cure the cube specimens until the day of testing. Test results indicates that water curing  as well as sprinkling (spraying) curing provided much better results than membrane  method of curing stream curing . The rate of drying was significant when the specimens were subjected to membrane method of curing. This thus hampered the hydration process and thus affected the compressive strength property of the hardened concrete. The highest compressive strength and density, followed by wet covering, sprinkling, then uncured for two days, with the totally uncured cubes having the least compressive strength and density as well as highest shrinkage limit.
