Mix proportioning for a concrete of M25 grade is given in A·I to A-ll. A·I STIPULATIONS FOR PROPORTIONING. a) Grade designation : M25 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 300 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.50 (Table 5 of IS 456:2000)
Jul 26, 2020· Normal grade of concrete are based on nominal mix ratio of cement, sand and aggregate have comparatively lower compressive strength than standard grade of concrete. Normal grade of concrete are M25,M20,M15,M10,M7.5 & M5 generally based on nominal mix proportion of cement sand and aggregate.
Jun 05, 2020· Cement, Sand, Coarse aggregate, and water with a suitable proportion of water. All of these components are mixed according to batching or Concrete grade table, Maybe M10, M20, M25, M30, etc. Mostly M25 and M30 always used in construction industries for multistory buildings. Must ensure these points:- ⦁ Keep care of the water-cement ratio.
