Jul 20, 2018· Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

Aggregate Crushing Value Test

Aggregate Crushing Value Test

It is a fact that parent rock compressive strength does not exactly indicate the strength of aggregate in concrete. For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner. This testing method is known as an aggregate crushing value test.
