Normal weight of concrete in mpa
WebSITUATION. The basic data for proportioning trial batches for normal weight concrete with an average with an compressive strength of 35 MPa at 28 days are as follows: Slump = 75 mm to 100 mm Water- cement ratio by weight = 0.48 Specific gravity of cement = 3.15 Specific gravity of coarse aggregate 2.68 Specific gravity of fine aggregate = 2.64 ... WebEach concrete grade e.g. C30/37 is characterized by two equivalent strengths, which in this specific example are 30 MPa and 37 MPa. The first is the characteristic strength f ck of a standard concrete cylinder and the latter is the characteristic strength of a standard concrete cube.
