Compressive Strength - an overview | ScienceDirect Topics
Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Table 3 shows the resulting compressive strength at 1, 3, 7 and 28 days for each blend and for the reference cement. Compressive strength is not reported for raw gypsum (C 0 G 100) and raw limestone (C 0 G 0) as these results are not relevant in cement formulations. These results show higher values than standard results because of the shape of ...

So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test
