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.

Learn MoreWhen you mix concrete, wear protective eyewear, gloves, and a face mask, since the dust can be caustic. For some people, the biggest challenge to address when they mix concrete will be lifting the product (it comes in bags that are heavy).
