Concrete Crushing - an overview ScienceDirect Topics

2010-8-7  An analysis of the abrasive wear of concrete floors has revealed that high-intensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance. 280 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of the concrete; rather, the properties of the mortar fraction are

Crushing Concrete Cube or Cylinder at 28 days

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 ...
