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. 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.

Concrete Strength What is the Compressive Strength of Concrete The strength of concrete is measure in terms of pounds per square inch or PSI. PSI is a measure of compressive strength, or the ability of the material to carry loads and handle compression. 1. 2500-3000 PSI Most concrete has a PSI rating of 2500 to 3000.
In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone. It is difficult to find reliable records of tests of sand and gravel concrete, 1 to 4 and 1 to 5, such as is used in making blocks the following figures show.
The reading at failure is the maximum compressive strength of the concrete. BS EN 12390-2 2009 BS EN 12390-32009. The concrete minimum compressive strength will be specified by the clientdesigner in a specific format. An example of this is given below C4050.

That tensile strength is the basis for its ability to resist bending, or its flexural strength. ACI 207R, Effect of Restraint, Volume Change, and Reinforcement on Cracking of Mass Concrete, states in Chapter 3 that concretes tensile strength is often taken as 6.7 times the square root of its compressive strength. It also notes that where a.
