· · 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 .
Rock Compressive Strength Table. 4 Widely varying correlations of unconfined compressive strength to point load index were found by rock type with some rock types showing no correlation The correlation for all data combined is markedly superior to that for any individual rock type.
The compressive strength of ice,, to MPa at O°C and to MPa at 50°C was quite less in comparison to compressive strength of the rocks tested. But tensile strength of ice,, MPa at O°C and MPa at SO°C is quite near to tensile strength of rocks tested", Therefore, it can be said that ice contributed to the
Sriapai et al. (2012) demonstrated that a considerable increase in temperature, reaching close to 200°C, caused a linear decline in both the compressive and tensile strength of salt rock mass.
The rock hardness of basalt is 6 on the Mohs scale and can be seen through a combination of its compressive strength 100 300 Mpa (Megapascal) its tensile strength 10 30 Mpa and its shear strength 20 60 Mpa which denotes that depending on the mineral makeup basalt rocks fall in the strong very strong egory

Compressive strength is one of the most important properties of concrete and mortar. The strength of the binder (cement) ... Materials such as concrete and rock are often evaluated using a compressive strength test and in these cases, fracturing occurs.
compressive strength of the intact rock pieces. For hardrock masses, Hoek and Brown [15] recommend a value of for a. In order to use the Hoek2Brown criterion for estimating the strength and deformability of jointed rock masses, ''three properties'' of the rock mass have to be estimated. These are: (1) the uniaxial compressive ...

· Compressive Strength of bricks. Generally, bricks have high compressive strength in the range of N / mm 2 to 140 N/mm 2. If the crushing strength of the bricks is less than 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.
· In quarries, uniaxial compressive strength is a crucial parameter in the analysis of geotechnical problems involving rock stability and rock blasting design. This study aims at establishing the empirical models of uniaxial compressive strength fits on rebound hammer number that can be used to predict uniaxial compressive strength of granitic rock at Lugoba Quarry.

These four test methods cover the determination of the strength of intact rock core specimens in uniaxial and triaxial compression. Methods A and B determine the triaxial compressive strength at different pressures and Methods C and D determine the unconfined, uniaxial strength.
