Aggregate Crushing Value Test
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 Test
The primary purpose of using coarse aggregates is to enhance the strength of the concrete. Moreover, the coarse aggregates will easily blend with other concrete ingredients and make it as a homogeneous element. The impact value test has been conducted on aggregate to determine its bearing capacity against sudden impact.

Different grade Of Concrete And Their Uses
Grade of concrete is defined by the strength and composition of the concrete.It is also defined as the minimum crushing strength of 150mm concrete cube after 28 days of curing.It is denoted by prefixing M to desired strength in MPa. For example, if there is a concrete mix with compressive strength of 15MPa, then its grade will be represented by M15.
