Contact SupplierThe grade of concrete is understood in measurements of MPa, where M stands for mix and the MPa denotes the overall strength. Concrete mixes are defined in ascending numbers of 5, starting at 10, and show the compressive strength of the concrete after 28 days.

Contact SupplierTo make ease in understanding we are finding the Concrete mix design of M20 grade concrete. The Concrete mix ratio for M20 grade of concrete is 1:1.5:3 that mean 1 part of cement, 1.5 part of sand (fine aggregate) and 3 parts of aggregate (crushed stone) in volume and then batched for mixing.

Contact SupplierWe use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting. In …

Contact SupplierThe water to cement ratio is calculated by dividing the water in one cubic yard of the mix ( in pounds) by the cement in the mix (in pounds). So if one cubic yard of the mix has 235 pounds of water and 470 pounds of cement- the mix is a .50 water to cement ratio.

Contact SupplierCould you please send me the mix ratio for concrete grade 10, 15, 20, 25, 30, 35 and 40. Also if i could have a chart showing tolerance for meeting the strength at day 7, 14, 21 and 28. Thank you, as i look forward to your urgent response.
