From the grain size distribution analysis, the rock crushing of basalt 1 in the product after crushing increased the proportion of non-flaky and cubical grains compared to the original sample (except for the coarsest grain class) from about 60 to about 80%, which was associated with a general decrease in the content of especially non-flaky non ...

What is basalt rock? Basalt is an igneous rock that formed from the solidification and cooling of molten rock material (lava or magma). Basalt is typically a dense dark rock colored blue, grey-blue, dark-grey or black with a fine-grained texture. Crushed basalt is used for a wide variety of purposes.

Results of the tests showed that the increase in particle size increases the strength and decreases the axial strain at failure and crushing of particles. The study also showed that crushed basalt, sheared under plane strain conditions, indicated higher strength than that tested under triaxial compression.
