Testing the Compressive Strength of Concrete — What, why ...
The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the crosssectional area resisting the load and reported in units of poundforce per square inch (psi) in US Customary units or megapascals (MPa) in SI units.

ommpression straigth of basalt rock
The rock hardness of basalt is 6 on the Mohs scale, and can be seen through a combination of its compressive strength: 300 Mpa (Megapascal), its tensile strength: 30 Mpa, and its shear strength: 60 Mpa, which denotes that depending on the mineral makeup, basalt rocks fall in the strong .
