What is the mix ratio for M30?
M30 Grade of Concrete Mix Design Calculation Formula Cement Content = 360 / 3.15 x 1000 = 0.114 Cu. M. Water Content = 140 / 1.00 x 1000 = 0.140 Cu. M.
What is the ratio for C35 concrete?
C35 ratio (must use 42.5 grade cement or above): cement: sand; stone: water = 1:1.37:2.78:0.46 (weight ratio): cement: 424kg; sand: 581kg; stone: 1179kg water: 195kg. Usually specified at design stage, this form of ready mix concrete is designed to comply with a compressive strength denoted by the class of mix.
How do you make a m40 concrete?

What is the difference between C30 concrete and M30 concrete?
C 30 is the compressive strength for a particular cube where as M 30 gives the characteristic strength of the concrete mix. C30 is the strength value for a single cube whereas the M 30 is 5 percentile value of strength several cubes of same mix tested as per Indian Standard.
