Jan 04, 2013· The average of the values of compressive strength (mean strength) from the graph is 40 MPa. The characteristic strength (fck) is the value in the x-axis below which 5% of the total area under the curve falls. From the graph we can clearly say that 30 MPa is the characteristic strength of the given concrete mix. The value of fck is lower than

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.
