Apr 01, 2018 The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or than 60 Mpa. The specified strength should be achieved at.Get Price

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.Get Price
