Experimental study on the influence of the shape and size specimen and the type of cement used on the conversion factors of compressive strength of concrete specimens

Compressive strength test of concrete is one of the most important tests for controlling the quality of concrete in construction structures and, moulds with different shapes and dimensions (cubic and cylindrical) are used to provide experimental specimens based on the workshop conditions and the reg...
