The strength of the stone is tested to determine its resistance to crushing and bending. The density, or specific gravity, is tested to design a support system capable of carrying the weight of the stone. The amount of water the stone will absorb (absorption rate) will help determine the resistance of the stone

Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

If a strong correlation between impact strength and the crushability of rock can be found, engineers working in crushing plant can easily predict rock crushability from the impact strength test. The main objective of this research is to investigate the possibility of estimating the crushability of rocks from the impact strength test.

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.
