One sample consists of 3 cubes, prepared and tested as per Clause 15.2.2 of IS 456:2000 or as per the project specification.
To be maintained as required depending on site conditions and type of construction work.
Must comply with the compressive strength values given in Table 11 of IS:456.
M-20 grade Ready Mix Concrete is a medium-strength concrete mix widely used for reinforced concrete structures like beams, slabs, and columns. It has a compressive strength of 20 MPa (Mega Pascals) after 28 days of curing, making it suitable for residential, commercial, and light structural applications. The mix ratio for M-20 is 1:1.5:3 (Cement:Sand:Aggregate).
M-20 grade RMC provides a balance between cost-effectiveness and strength, making it an ideal choice for both light structural work and general construction where higher compressive strength is not essential.
