2016-09-06· Recommended mix proportion of ingredients for grade of concrete M25: From Compressive Strength vs. c/w graph for target strength 31.6 MPa we get, W/c = 0.44. water content = 197.4 kg/m 3. Cement content = (197.4/0.44) = 448.6 kg/m 3. Volume of all in aggregate = 1 – [{448.6/(3.15 x 1000)} + (197.4/1000)] = 0.660 m 3. A reduction of 0.05 in w/c will entail and increase .

2019-03-08· One easier solution to remember concrete ratio. We know that M15 ratio is 1: 2: 4 Above the M15 only decrease.0.5 in sand and aggregate 1low M15 we increase sand 1 and aggregate 2. It's the easiest form remember the ratio of concrete.

Grade of concrete is defined as the minimum strength the concrete must posses after 28 days of construction with proper quality control. Grade of concrete is denoted by prefixing M to the desired strength in MPa. For example, for a grade of concrete with 20 MPa strength, it will be denoted by M20, where M stands for Mix.
