2021-10-21  So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 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

Stone Testing

since the strength may vary when the stone is wet, the strength tests (i.e. 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

Relation Between Density and Compressive Strength of

Compressive strength increases with days. More compressive strength is found from SC concrete than BC concrete. When compressive loading is applied to BC concrete, mortar and aggregate fails together. As brick aggregate has lower compressive strength than stone, brick start to fail earlier than similar type of SC aggregate concrete.
