What is Compressive Strength? Matmatch

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 cases ...

ASTM C39 Concrete Cylinder Compression Testing ADMET

ASTM C39 | Concrete Cylinders | Compression Testing. ASTM C39 determines the compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a unit weight in excess of 50 lb/ft3 (800 kg/m3). A compressive axial load is applied to molded cylinders or cores until failure occurs.
