Jul 20 2018 compressive strength test this test is vital for evaluating the stones resistance to crushing loads a wall stone has to bear the compressive load of the stones 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 a

The compressive strength is the maximum load per unit area that the stone can bear without crushing a higher compressive strength indicates that the stone can withstand a higher crushing load the required values range from 1800 psi 1245 mpa for marble to 19000 psi 131 mpa for granite

Crushing strength of the stone per unit area is the maximum load at which the sample crushes or fails divided by the area of the bearing face of the specimen crystalline test on building stone at least four cubes of stone with side as 40mm are taken they are dried for 72 hrs and weighed they are then immersed in 14 solution of na2so4 for 2
