Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

Answer (1 of 3): Compressive strength is the load (measured in pounds/sq. in. or /sq.ft.) which the concrete (poured over a solid base) will support, without damage.

The crushing load is noted. Then crushing strength is equal to this crushing load divided by the area where the load is applied. At least three specimens must be tested, and the average ought to be taken as crushing strength. Also, read: What Are Walls | Classified of Walls | Load-Bearing Vs Partition Walls.

Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc. Test for compressive strength is carried out either on a cube or cylinder.

For a rock crushing strength of 50 MPa (highest strength simulated in this study), the maximum boulder impact force and transmitted loads on the flaky rocks are about 20% larger compared to that of bulky rocks. Flaky rocks are angular and restrict rotation, enabling force chains to sustain high loads. This implies that rounded rocks with high rock crushing strength may be more favourable to

compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area. Rock strength has been found to be size dependent because of the cracks and fissures that are often present in the material. This is illustrated from the results of tests on three rock types in Fig. 8.2. The size

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
