The "M" refers Mix and Number after M (M10, M20) Indicates the compressive strength of concrete after 28 days of curing and testing.. M indicates the proportion of materials like Cement: Sand: Aggregate (1:2:4) or Cement: Fine Aggregate: Coarse Aggregate.. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days.
The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand.
Different nations have their own grade of concrete. We will discuss some of them. 1.1. Grades of Concrete Based on IS The grade of concrete is the minimum strength that the quality controlled concrete posses after 28 days of the construction. There are different grades of concrete …
Assume We need 1 m3 of wet volume concrete of M25 Mix, (Mix Ratio, M25 = 1: 1 : 2) So Total Parts = 1+1+2 = 4 Parts which gives Dry volume that means before adding water content Volume of concrete = (1 Cement Part)/4 + (1 Sand Part)/4 + (2 Coarse Aggregate Part)/4

Concrete is classified into different grades like M5, M7.5, M10, M15, M20 concrete based on the strength of concrete. In concrete grades, the letter "M" stands for "Mix" (mix of Sand, Cement, and Aggregate) and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.
