RMC, that started evolving in the year 2000—the same year as m-sand, was scoping solutions to improve the quality of concrete. This led to increased demand for high quality sand and m-sand manufacturers. These manufacturers in turn, were forced to adapt new technologies to supply the fine grade material to capture the new demand.
693 kg of Sand required for 1 cu.m of M-20 grade concrete. 1344 kg of 20mm Aggregate is required for 1 cu.m of M-20 grade concrete. 180 litres of water is required for 1 cu.m of M-20 grade concrete.

M-Sand is cost-effective due to lower transportation costs and consistent availability. Disadvantages of M-Sand. Consider these factors if you wish to use M-Sand for your construction: The smooth and angular textures of M-Sand may require more water and cement to achieve the desired workability. This may lead to higher overall costs.

Generally, when the stone ratio is more than the sand, this concrete cures a little stronger than a 1:3:3 ratio. The difference is in the workability of the concrete. The sand tends to make the concrete a little more easier to work with. The less sand the rockier the mix is going to be. Cool things you can make by mixing your own concrete
The typical concrete mix ratio for making M15, M20 and M25 concrete is (cement : sand : stone): 1:2:4, 1:1.5:3 and 1:1:2 respectively according to volumetric analysis.
