What are the types of concrete grades.

Question

Accepted Answer

Concrete grades are classifications that indicate the strength and quality of concrete.

Concrete grades are determined based on the compressive strength of the concrete.
The most common concrete grades are M10, M15, M20, M25, M30, M35, M40, M45, M50, M55, M60, and M70.
The number in the concrete grade represents the compressive strength of the concrete in megapascals (MPa).
For example, M20 grade concrete has a compressive strength of 20 MPa.
Higher concrete grades are used for structures that require higher strength, such as bridges and high-rise buildings.
Lower concrete grades are suitable for non-structural applications like flooring and paving.
Concrete grades can also be classified based on the mix proportions of cement, sand, and aggregate used.
