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 …

(a) Crushing test for stones: The crushing strength of a stone greatly depends upon its texture and specific gravity. A stone of even texture arid of specific gravity greater than 2.7 can take heavy loads. Safe compressive loads on stones should be taken not more than one-tenth of the crushing loads determined by cube test.

Record this load. The Crushing strength or compressive strength is given by the formula as: C= P/A. Where, C = compressive strength P = Load at failure A = cross-sectional area of bearing face of the specimen. Then the average value of the six specimens is calculated and the result is recorded for that stone sample.

Crushing strength of stone: It is defined as load per unit area at which stone starts cracking. It depends on: 1. The texture of stone ensures whether the stone is rough or smooth hence friction between the surface of the stone and the CTM machine depends on the texture and hence crushing strength of stone also depends on texture. 2.
