Dear All,

In IS-456:2000, we have concrete grades up to M80 but in ACI-318-19 we have concrete grades up to 5000 psi.

5000 psi = 35 N/mm2.

Kindly explain, why this difference.

Also, for grades M55 and above what special mix design do we need to follow other than IS-10262?

Thanks & Regards,
Ramu.
