ABSTRACT
This study discussed the effect of curing condition on capillary water absorption of concrete incorporating locally available materials. Compressive strength and ultrasonic pulse velocity (UPV) as part of mechanical and durability properties of concrete were also investigated. The engineering properties were conducted on concrete under three different curing conditions at different curing ages of 2 days, 7 days and 28 days. The three different curing conditions were water curing, dry curing and gunny-covered curing. According to the results obtained concrete under water curing condition demonstrated lower capillary water absorption (CWA) at 2 and 7 days ages and concrete under gunny-covered condition demonstrated lower CWA at 28 days age compared with the other curing conditions. It is interesting to see that the compressive strength (38 MPa) of concrete was almost the same at 28 days age under gunny-covered and water curing conditions.
