Uniaxial Compressive Strength an overview ...
The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heattreated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c and tensile strength σ t ...

Mar 31, 2019· Compressive strength is important as it is the main criteria used to determine whether a given concrete mixture will meet the needs of a specific job. Concrete psi. Pounds per square inch (psi) measures the compressive strength of concrete. A higher psi means a given concrete mixture is stronger, so it is usually more expensive.

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.
