Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of 5.5 N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 3.5 N/mm 2 it must not be used. A field test about strength of the bricks is to fall the brick from a height of 1 meter and it must not break in to pieces.

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

Rock strength and porosity have good correlations for various rocks, and porosity can be obtained from lab tests or from density and sonic logs. In the following equations, the rock strength UCS is in MPa and porosity is in percent (%).

It gives the shear strength of rock as a function of confining pressure. In this test the specimen doesn’t require perfect square or smooth ends. Load is applied parallel to the axis of core. As the load is applied to the plunger, 2 sets of complex fractures surfaces form along the two planes of imposed shear.

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0).Lithology is commonly derived during log analysis, so m may be estimated (Table 1).What is needed still is an initial measure of rock strength provided by C 0. C 0 can be estimated from porosity or sonic velocities, but many
