What do you mean by M20 concrete?
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
What is heavier sand or concrete?
Concrete is generally heavier than sand. The density of concrete typically ranges from about 2,200 to 2,500 kg/m³, while dry sand has a density of approximately 1,500 kg/m³. Therefore, for the same volume, concrete will weigh significantly more than sand.
What is concrete mixing ratio in M 40 concrete?
