Read MoreApr 06 2020 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 12.45 MPa for marble to 19000 psi 131 MPa for granite.

Read More1. Granite. Granite is an igneous rock which is formed by the solidification of magma at a considerable depth from the earths surface. It is hard and durable. It is available in different colors. The color of granite varies according to the amount of feldspar in it. It can be polished nicely. The compressive strength of granite is about 75 .

Laboratory tests and field studies on excellent quality Lac du Bonnet granite reported by Martin and Chandler 1994 show that the in situ strength of this rock is only about 70 of that measured in the laboratory. This appears to be due to damage resulting from micro-cracking of the rock which initiates
