diabase compressive strength

The Strongest Rock in the World Rockhound Resource

2 天前  The strongest rock in the world in compression is Diabase, which can stand up to 350 MPa. Diabase is a kind of fine-grained igneous rock. Close behind diabase in compressive strength come other fine-grained igneous rocks like Diorite, Gabbro, and Basalt. Interestingly, the one non-igneous rock in this super strong group is Quartzite.get price

The effect of water on the compressive strength of diabase

1968-10-1  The compressive strength of water soaked diabase is found to be about 60% of that of diabase dried at temperatures greater than 190°C. Several solvents other than water failed to cause a decrease in the strength of diabase. This suggests that water is involved in a chemical reaction during the fracturing process, and that its effect is not simply capillary action.get price

Diabase (Dolerite) Archae Solenhofen ([email protected]) (Last modified April 3, 2001) Diabase is a fine-grained intrusive igneous rock of a composition similar to basalt, but is slightly more coarse-grained than basalt.The rock consists of the minerals calc-plagioclase (bytownite to labradorite) and pyroxene (commonly augite, pigeonite, and hypersthene) with apatite, magnetite, andget price

2015-6-4  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 sonic velocities, but get price
