  • What is the mix ratio for grade C30 concrete? - QuoraWe have nominal mix or standard mix only upto M25 or C25 as you call and that is 1:1:2 , cement:sand: aggregate. C25 will have a compressive strength of 25Mpa after 28days of curing. C30 is a concrete of 30Mpa compressive strength at the endof 28days. And that can only be done by design mix and no standard mix is available.
