May 16, 2007· It all depends on the purpose for which the concrete is used. Usually 1:3:6 is used for flooring with large size crushed stone (40 mm nominal size), 1:2:4 is used for columns, beams, roof slabs etc. The mix 1::3 is used for water tanks. M refers to mix and the number denotes characteristic strength of the concrete.

Dec 08, 2017· We all know that on mixing cement with sand, stone/aggregates and water, a paste will form which can be used to bind the building materials together. This paste is also called as concrete. The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed.

Generally, increased strengths are achieved by adding more cement, although other additives can help. A M20 concrete cannot be theoretically be stronger than M40 as it is being designed initially for a lower strength gain; if it achieves a higher strength than 20 N/mm2 at 28 days, then it is not really an M20 mix.
