We discuss about concrete grade types according to their use, there are two types of concrete grade given following:-, 1) PCC :- it is plain cement concrete which has mixture of cement sand and aggregate which is used for mainly flooring and formation of different types of Pathways. ■1) ordinary concrete grade :– it is simple type of concrete grade mainly used for flooring of surface and formation of flat base for footing and filling , concrete grade like M5 M10 m15 and M20 is ordinary concrete grade, in which M stand for mix and there numerical figure 5 10 15 and 20 stand for comprehensive strength of concrete in 28 days of curing time. Minimum grade of concrete for PCC:- M5 is very lean mix concrete and can be used in any nonstructural work, but it is banned today due to shrinkage issue, so minimum grade of concrete is M7.5 which is used for PCC. A design mix concrete is preferred over a nominal mix concrete especially where the concrete is above M20 grade and also where the requirement is of the different workability and risk of deviation. 1 : 5 : 10. 1:4:8 (m7.5), 1:3:6 (m10) and 1:2:5 (m15) is concrete mix ratio used for floor, PCC & none RCC structure. M5 M10 and m15 concrete is not used for RCC work it is only used for PCC work and nominal mix concrete M20 is only ordinary concrete grade which is used in both PCC and RCC work construction of low rise building. As per IS 456:2000 Standard Concrete grades are M 25, M 30, M 35, M 40, M 45, M 50 and M 55. If we mention M10 concrete, it means that the concrete has 10 N/mm2 characteristic compressive strength at 28 days. 1:1.5:3 (m20) … Concrete mix ratio is used as PCC (plain cement concrete) in Roadways Pathwas formation and for flooring of house and also concrete mix ratio is used as RCC for the formation of roof slab, Foundation, footing, beam and column. In this post, we are going to explain that in detail. Rapid strength concrete is mixed according to the exact look and grade desired when clients are ready to receive it. Hi-Grade Materials is the smart choice for ready-mix concrete, sand and gravel needs. The “M” denotes Mix design of concrete followed by the compressive strength number in N/mm2.
