Get Price· So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi ( MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test

Get Pricematerial is compressed between the platens of a testing machine as illustrated in Fig. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the crosssectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material.
Get Pricesince the strength may vary when the stone is wet, the strength tests ( compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C ±2°C (140°F ±2°F) for at least 48 hours or
Get PriceThe compressive strength of the rock used is almost always equal to or greater than concrete. The mortar used will typically be a type of portland cement and will be weaker than the rock. Stone masonry deteriorates by weathering (breaking into small particles), spalling (small sections of rock popping out), or splitting (separations occurring either at seams in the rock or along mortar joints).
