Where to use Ready Mix Concrete M20
How to choose the right ready mix concrete m20
M20 grade concrete has a characteristic compressive strength of 20 MPa at 28 days. It is the minimum grade recommended for RCC work as per IS 456. For residential buildings up to G+3 in normal exposure conditions, M20 is commonly used for slabs and beams.
Ready mix concrete (RMC) offers several advantages over site-mixed concrete: consistent quality through computerized batching, faster pouring, less labour, and no material storage hassle. In congested areas of Mumbai where site space is limited, RMC is almost always the practical choice.
Order RMC based on your structural engineer's specification. M20 is typically used for residential slabs, small columns, and foundations. For larger structures or aggressive environments, your engineer may specify M25 or M30 instead.
