The sample average unrestrained compressive strength for 45 specimens of a particular type of brick was com- puted to be 3107 psi, and the sample standard deviation was 188. The distribution of unrestrained compressive strength may be somewhat skewed. WebbRecent compressive strength testing on a range of sandstones, where stress and strain measurements have also been made, have revealed that the mode of failure appears to change, depending on the degree of saturation. In wet conditions, failure occurs by vertical splitting, and is accompanied by an increase in Poisson’s Ratio.

WebbCompression ROCK STRENGTH • The peak stress is the strength of the rock. – It may fail catastrophically if the load frame is “soft”. Example below is for a “stiff” frame. • The compressive strength of rock is a function of the confining pressure. • As the confining pressure increases so does the strength.
