What is Compressive Strength?
Compressive strength refers to the ability of a certain material or structural element to withstand loads that reduce the size 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 .
