Q2. Different grade of concrete
Ans. 
Different grades of concrete are classified based on their compressive strength.
• Concrete grades are denoted by M followed by a number, such as M20, M30, etc.

• Higher grade concrete has higher compressive strength.

• Different grades are used for different types of construction projects.

• Common grades include M20, M25, M30, M35, and M40.

• Each grade has a specific mix ratio of cement, sand, and aggregates.
