concrete. A properly proportioned concrete mix should possess these qualities: 1. Acceptable workability of the freshly mixed concrete 2. Durability, strength, and uniform appearance of the hardened concrete 3. Economy Understanding the basic principles of mixture design is as important as the actual calculations used to establish mix proportions.

Concrete mixes are classified by their grade having specified crushing strength at 28 days as measured in standard conditions with 150 mm × 150 mm × 150 mm size cube, which means the grade of concrete corresponds to its characteristic compressive strength . M-20 shows the crushing strength of that cube having size 150 mm at 28 days is 20 N/mm2.

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. These grade of concrete is converted into various mix proportions. For example, for M20 concrete, mix proportion will be 1:1.5:3 for cement:sand:coarse aggregates.

Builders also measure the strength of the resulting concrete in grades. The higher the grade, the stronger the concrete is. The mix ratio of the concrete determines its grade. A concrete grade of M25, for instance, needs a mix ratio of 1 : 1 : 2. This indicates a ratio of one one part cement, one part water, and two parts coarse aggregates.
