Civiconcepts - Make Your House Perfect With us

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.

How to Make 32 MPA Concrete | Hunker

And, 32 MPa converts to 4,643 psi. So the brief answer, without discussing air entrainment or surfactants, is that in the United States you mix widely available 5,000 psi (or 34.5 MPa) cement with the proper amount of fine and course aggregates and water and then you allow that concrete to cure to full strength, which takes about a month.
