Standarad concrete is 7 m20 to m60.

High strength is m65 t0 m80.

Ordinary strength 3m m10 to m20.

What is the ratio of M30, M35 and M40?

Soniya said:   1 decade ago
Above M30 Mix design is done because 5 ingredient of concrete will start above M30 i.e. cement, aggregates, water, admixture.

Govardhan said:   1 decade ago
How M30, M35 can be treated as nominal mix?. It falls under the category of design mix.

Anish said:   1 decade ago
How can we find out the ratio of M30, M35, M40, M50?

SABYASACHI SEN said:   1 decade ago
Nominal concrete grades are from M5 TO M25 maximum. But still we need to have mix for M 25 also.

Here we take std concrete which starts from M 25 TO M 55 (i.e. 7) from IS 456:2000 table 2.
