What is the crushing strength of granite? Our Planet Today
网页2022年4月15日 What is the crushing strength of granite? 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 1,800 psi (12.45 MPa) for marble to 19,000 psi (131 MPa) for granite.
