According to Abram's Law water-cement law, lesser the water-cement ratio in a workable mix greater will be the strength. If water cement ratio is less than 0.4 to 0.5, complete hydration will not be secured. Some practical values of water cement ratio for structure reinforced concrete 0.45 for 1 : 1 : 2 concrete; 0.5 for 1 : 1.5 : 3 concrete

18/06/2022Fine aggregate vs. coarse aggregate A typical concrete mix contains 60 to 80 percent sand and gravel, also known as an aggregate. This aggregate compound is more than filler. It plays an important part in the concrete's composition. The amount of sand and gravel in a bag of concrete determines the mixture's strength and texture.

The strength of this concrete mix is determined by the proportion on which these cement, sand, stones or aggregates are mixed. There are various grades of concrete available in the market based on these ratios. Some of them are: M10, M20, M30, M35, etc. So, what really does M10 or M20 mean or represent. "M" stands for "mix".

Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30 Higher the Aggregate/Cement ratio leaner the concrete mix, as cement content is lower. Concrete mix can be made more workable by fine tuning Aggregate/Cement ratio.
