2018-4-1 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 more than 60 Mpa. The specified strength should be achieved at 28

Contact2013-3-6 The crushing strength of concrete is influenced by a number of factors in addition to the water/cement ratio and the degree of compaction. The more important factors are: (1) Type of cement and its quality. Both the rate of strength gain and the ultimate strength may be affected. (2) Type and surface texture of aggregate.
