29-05-2021· For example, for a grade of concrete with a strength of 20 MPa, it would be denoted by M20, where M stands for Mix and 20 is the overall strength of the concrete in Newton. Major ingredients of concrete are binding material (like cement, lime), fine aggregate (sand), coarse aggregates (crushed stone, jelly), and water.
In this article we are discussing about concrete mix ratio and ideal mix concrete. Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. To make concrete, four basic materials you need: Cement, sand, aggregate, water, and add-mixture.
For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate. The proportions are either by volume or by mass. The water-cement ratio is usually expressed in mass
Coarse aggregate ratios for different Zones of Fine aggregates are given in Table 3 of IS10262. These are ratios are valid for 0.5 Water-cement ratio. Table 3 Volume of coarse aggregate to total aggregate ratio for Mix Design of M20 concrete – IS10262. For aggregate = 20mm, Fine aggregate= Zone II, Water-cement ratio = 0.50.
02-05-2020· Different grades of concrete have different proportions. Same, Different grades of Concrete Mix design need a different quantity of water. Don't forget, excessive use of water in concrete may lead to shrinkage and creep. M20 Grade of Concrete requires approximate 200liters or 53 gallons of water
