How to Check Compressive Strength of Concrete The Compressive strength of concrete cube test is very important to test that provides an idea about all the characteristics of concrete By performing this test we can predict about manufactured Concrete is done properly or notA compressive axial load is applied to molded cylinders or cores until failure occurs The compressive strength of the specimen is calculated by dividing the maximum load achieved during the test by the cross sectional area of the specimen The results of this test method are used as a basis for quality control of concrete
اطلاعات بیشترIn China the compressive strength tested by the cube 150mm or 100mm and the ratio between the strength test on cubic sample is 10/095。 According to some experiments the strength of cube is about less 10MPa than that of cylindrical sample S two different high strength concrete mixtures were used The expected cube compressive strength of concrete mixes is m15 and m20 From the literature review it is observed that researches have been attempted on various aspects of flakiness of the aggregat But it
