What is the ratio of M15 concrete?

  • 4

M15 should not be used in structural concrete. In addition, it is better to mix design instead of using the nominal mixes mentioned by others!

      1:2:4 is all about the proportion of the concrete while M15 is the compressive strength of whatever mix you use. In this case (15 N/mm2)

      M15 ratio is 1:2:4 in which one part is cement, 2 part is sand and 4 part is aggregate mix with water

      Nominal mix for m15
      1:2:4
      Dry volume for concrete 1.51
      Cement 315 kg ppc
      Sand .43 m³ × density of sand
      Aggregate .86m³ × density of aggregate
      20mm,10mm ratio use as workable trial mix
