Q1. What is compressive strength of brick
Ans. 
Compressive strength of brick is the maximum load a brick can withstand before it breaks.
• Compressive strength is measured in N/mm² or MPa.

• The strength of a brick depends on its composition, manufacturing process, and age.

• The average compressive strength of a common brick is around 5-10 N/mm².

• Engineering bricks have a higher compressive strength, usually around 50 N/mm².

• The compressive strength of a brick is important i...read more

Q2. What is M stand for in concrete
Ans. 
M stands for Mix in concrete.
• M refers to the mix ratio of cement, sand, and aggregate in concrete.

• For example, M20 concrete has a mix ratio of 1:1.5:3 (cement:sand:aggregate).

• The higher the M number, the stronger the concrete.

• M is also used to indicate the compressive strength of concrete, such as M30 or M40.

• The M stands for 'mix' or 'mixture'.
