Read More20191119 Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix especially the watercement ratio and time and quality of the curing compressive strength of concrete can be obtained up to 14000 psi or more. Commercial production of concrete with ordinary

Read More20191120 Concept and significance of the Aggregate crushing value test. The aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under
