What are the characteristics compressive strength of concrete ?

Question

Accepted Answer

Compressive strength is a measure of the ability of concrete to resist loads that tend to compress it.

Compressive strength is typically measured in pounds per square inch (psi) or megapascals (MPa).
The strength of concrete increases with age, with most of the strength gain occurring within the first 28 days.
Factors that affect compressive strength include the water-cement ratio, curing conditions, and the type and amount of aggregate used.
The minimum compressive strength for concrete used in buildings and other structures is typically 2500 psi (17.2 MPa).
