THE UNIAXIAL COMPRESSIVE STRENGTH OF SOFT ROCK

Soft rock is a term that usually refers to a rock material with a uniaxial compressive strength (UCS) less than 20 MPa. This low strength range might be influenced by physical characteristics, such as size, saturation, weathering and mineral content. A number of uniaxial compression tests have been conducted onto soft rock samples.

The ratio of secondary compression index to compression index is independent of whether compression results from overcoming interparticle friction through interparticle slip, from overcoming particle strength through particle damage, or both; and therefore it is a constant independent of the effective stress range.

Effect of aggregate type on Compressive strength of concrete

Normal strength concrete made with basalt and gravel gave similar compressive strength while the concrete containing limestone attained higher strength. The effects of content and particle size distribution of coarse aggregate on the compressive strength of concrete have been investigated (Meddah, Zitouni, and Belâabes 2010).
