Properties of concrete - Wikipedia

Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to Tensile strength which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength ...

Properties of Concrete Blocks — Strength

compressive strength of concrete increased with age. As the curing time increases, the reaction between cement and water continues thereby forming more C-S-H gel which improves the bond between the cement paste and the aggregates, thereby increasing the compressive strength. It is also seen that the compressive strength of concrete reduced
