Crush Testing - Compression Strength Testing of Concrete ...

A crush test (more accurately a compressive strength test) is the way United Scanning usually answers this question. The compressive strength of a material, in this case concrete, is the ability of the material withstand or carry loads that would tend to compress it. United Scanning acquire a core sample of the concrete
