Relation Between Compressive and Tensile Strength of Concrete

Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the water-cement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more. Commercial production of concrete with ordinary ...

For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f’ m of 1750 psi to 2000 psi for CMU units with 2000 psi compressive strength). The compressive strength of the masonry units is the largest factor, by far, in masonry assembly compressive strength.

STRUCTURE magazine | Mortar Compressive Strength

Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.
