What are the grade of concrete?

Question

Accepted Answer

The grades of concrete are a classification system used to indicate the strength and quality of concrete.

Concrete is classified into different grades based on its compressive strength.
The most commonly used grades of concrete are M20, M25, M30, M35, and M40.
The letter 'M' stands for mix, and the number after it represents the characteristic compressive strength of the concrete in megapascals (MPa).
For example, M20 concrete has a characteristic compressive strength of 20 MPa.
Higher grade concrete indicates higher strength and durability.
Different grades of concrete are used for different applications, such as residential buildings, bridges, dams, etc.
