The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,1719].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...
Crushing strength: For a good building stone, the crushing strength should be greater than l000kg per cm2. 2. Appearance: Good building stone should be a uniform colour, and free from clay holes, spots of other colour bands etc capable of preserving the colour for longtime. 3. Durability: A good building stone should be durable. The

properties, however, tend to control the strength of the rock mass if discontinuities are widely spaced or if the intact rock material is inherently weak or altered. Dis-continuities within a rock mass, therefore, reduce its strength and stability and reduce the energy required to excavate or erode it.
