Compressive 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.
Besides preventing valuable natural resources from going to waste, using stone waste from stone processing plants in concrete helps reduce environmental pollution and, therefore, offers a convenient route to sustainable development. The present study aims to use granite waste (GW) in high-strength refractory concrete. Sixteen high …

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 …
Liu et al. conducted compression experiments on heat-treated granite and found that the compressive strength of granite decreased with temperature; however, compressive strength increased slightly at 100 °C, and 600 °C was the critical temperature for the brittle–ductile transition of stress–strain curve.
The Materials Specifications put forth minimum values for compressive strength for each stone type; for example, at least 1,800 psi (12.45 MPa) for marble and 19,000 psi (131 MPa) for granite. Compressive strength—or the load at which the stone fails—is usually much higher than the actual load the stone must resist.
DESIGN'NOTE'7:Characteristic'compressive'strengthof'masonry ' The following tables show the characteristic compressive strength of masonry in N/mm2 for common sizes of UK masonry units. Note that for some low strength units the characteristic compressive strength of the masonry can be slightly higher than the unit strength.
