Compressive Strength Test Of Concrete Detailed Guide
2 天前 · Simple. Assume, the approx weight of one concrete cube = 8 kg Then the volume of concrete = 0.15 x 0.15 x 0.15 = 0.0033 m 3; So for 1 m 3 = 8/0.0033 = 2400 kg/ m 3. Since the concrete weight itself has also been assumed for the structural calculations, if it exceeds the assumed value, then the load on the structure will likely increase.
