Abstract |
|
Compressive strength of concrete is the most important input data for engineering computations during the design of reinforced concrete structures. In this analysis, compressive strength of concrete is determined by the compressive testing machine. In this research work, we have constructed cubes as a specimen size of 150mm x 150mm x 150mm.We used two grades of concrete which are M20 and M25 grade of concrete. We tested cubes at 7, 14, 28 days of casting. The materials which are used in this study are OPC cement, coarse aggregate, fine aggregate and water. Concrete should be strong enough to bear the desired stresses within the permissible factor of safety. However, it is known that the variance of compressive strength test result by CTM becomes large and it is difficult to evaluate precisely the compressive strength, so we use average compressive strength. |
