This special project was aimed to study on concrete behavior in terms of compressive strength, moisture content, unit weight and proportion of coarse aggregate. In this study, two (110x110x30 cm3) specimens were prepared for testing. One was cure by ponding method. The other was cured by covering with plastic film. Next, at 28 day curing, twenty concrete samples with 5 centimetre diameter at 30 centimetre depth were cored from each specimens
