Get PriceCompressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
Get Price· Compressive Strength. Even though MSV is a veneer and does not carry structural load, ASTM C1670 includes a requirement that MSV units meet a minimum compressive strength as an indicator of product durability and consistency. Other concrete masonry units are manufactured and cured before being tested in compression.
