Triaxial strengths are difficult to obtain when the rock is very heterogeneous with respect to particle size and particle lithology and the samples are difficult to obtain and prepare. A fault breccia with clasts weaker than the matrix was investigated. It was found that its strength was related to the proportion of the blocks and the size of the specimen. The volumetric block proportion and

Intact rock strength . The uniaxial compressive strength of a rock material constitutes the highest strength limit of the rock mass of which it forms a part. It is determined in accordance with the standard laboratory procedures. For the purpose of rock mass classification, the use of the well -known point load strength index can be useful as the

Two rocks of the same type with the same resistance to crushing can offer different resistances to attrition. The resistance of a rock to fracture is approximately 1/10 to 1/30 of the ultimate resistance to crushing. Some physical and mechanical properties of rocks, important in technology are given in table-7.

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.

Typically, crushing stages are followed by milling stages if the materials need to be further reduced. Additionally rock breakers are typically located next to a crusher to reduce oversize material too large for a crusher. Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder.

The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall. [11] For design purposes, this compressive strength value is restricted by dividing with a factor of safety, whose value depends on the design philosophy used.
