· The M30 concrete mix ratio is a proportion of ingredients used to achieve a particular strength in concrete. The ratio is 1:0.75:1.5, which means for every 1 part cement, you need 0.75 parts sand and 1.5 parts aggregates when making 1 cubic meter of concrete. For Concrete mix design, we use, IS 456, and IS 10262.

Concrete Mixing Ratio for Beams. Typically, builders mix concrete for beams in a 1:1.5:3 ratio. 1 part cement. 1.5 parts sand. 3 parts aggregate. This ratio is ideal for strong structural applications such as reinforced concrete beams. If you need a balance between workability, strength, and durability 1:2:3 ratio will also work.
