Concrete Compressive Strength - an overview

Concrete compressive strength does not depend on the full hydration of its cement particles but essentially on their closeness. 10,11 In a concrete having a water/cement ratio lower than 0.42, hydration stops when there is no more water to hydrate the cement particles. Below this critical value of 0.42, very fine cement particles can be fully hydrated but only the surface of the coarsest ones

Concrete Mix Ratio: What Is It? What Is 1-2-3? ...And More

A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more

How to Calculate Quantities of Cement, Sand and Aggregate

With constant research and development in the field of cement technology and its manufacturing process ,a M20 mix of "1:1.5:3″(by volume) would be too rich,over engineered and uneconomical (~7.5 bags of cement per cum) and will ultimately result into a M30 concrete and above, the reason being latest generation of 53 grade OPC cement is ultimately giving a strength of 65 to 70 MPa at 28days.
