Max permissible flyash content as per MORT&H is 20% of cementious material. How can you take 25%

Max permissible flyash content as per MORT&H is 20% of cementious material. How can you take 25%

I did not find any limitations like this mentioned in MORTH nor anyone stopped me from doing such concrete.

Please provide the details of such limitation for concrete manufacturing and not for manufacturing of cement.

SSD Means Satchurated surface Dry Condition, Means Aggregate's surface is dry it won't observe water.
