K-400 grade concrete refers to a specific classification of concrete that can withstand a compressive strength of 400 kg/cm² (or approximately 40 MPa) when fully cured. This grade is commonly used in structural applications like beams, columns, and slabs due to its high strength and durability. The "K" typically indicates a standard grading system used in some regions, particularly in Asia.
concrete grade and strength are both revalent since if grade increase setting time will be less and curing to be done propely so that concrete strength will reach higher. If concrete grade is low curing to done longer days upto intial setting time to reach proper strength

The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance (withstanding a compression) of 30 N/mm2 per square millimetre in 28 days.

The grade of concrete for various concrete proportions areM10 - 1:3:6 (Cement:Fine aggregate:Coarse aggregate)M15 - 1:2:4M20 - 1:1.5:3M25 - 1:1:2
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
