Ultimate Compressive Strength Of Rock

FOB Reference Price: Get Latest PriceGet Latest Price

Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the sie of that material or structural element when applied. A force is applied to the top and bottom of a test sample until the sample fractures or is deformed.. Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases
