Rohan Builders Junior Engineer Civil Interview Questions and Answers

Q1. What is the grade of concrete
Ans. 
The grade of concrete refers to its strength and is determined by the ratio of cement to sand to aggregate.
• The grade of concrete is typically denoted by a number followed by the letter 'M', such as M20, M30, etc.

• The number in the grade represents the compressive strength of the concrete in megapascals (MPa) after 28 days of curing.

• For example, M20 concrete has a compressive strength of 20 MPa, while M30 concrete has a ...read more
