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. More

To increasing the compressive strength of concrete, we must increase cement and decrease water quantity. For example, M15 grade of concrete when we use50 kg of cement,480 kg aggregates and32 liters water we get15N/sq.mm compressive strength after28 days by15 cm. cube test.

A CLSM compressive strength of 50 to 100 psi is equivalent to the bearing capacity of a well-compacted soil. Maintaining CLSM strengths at low levels is critical in those projects where future excavation will be required, and therefore it is often critical that mixtures be proportioned in a manner so as to minimize later-age strength increases.
