Frequently Asked Questions
How much sand for M20 concrete per cubic meter?
M20 concrete (1:1.5:3) requires approximately 0.42 cubic meters of sand per cubic meter of concrete.
How many CFT of sand per bag of cement?
For M20 mix: approximately 1.5 CFT sand per 50kg cement bag.
What is the difference between M15, M20, M25 concrete?
M15 = 15 N/mm² strength, used for plain concrete. M20 = 20 N/mm², most common for slabs. M25 = 25 N/mm², for heavy structural work.
