Dear all,

Can we use higher grade M40 for flat plate and lower grade M25 for columns. The use of higher grade in slab is to avoid punching shear failure. And I have height restrictions, I can't increase the slab thickness.  

Anyone pls let me know, can I reduce the grade of concrete in column. pls share if you have any reference and any IS code provisions.

Thanks in advance.

Regards,

Vinay

Dear Sir,
    The discussion at https://www.sefindia.org/forum/viewtopic.php?p=8916 talks about similar topic albeit considering higher strength for column and lower for slabs and beams which may sometimes be the case in high rise buildings. It includes reference to ACI code for the same.

    In your case, the slabs are of higher grade compared to column. At the joint, only the higher grade concrete will be present since it will be concreted along with the slabs. Hence, I think there is no issue with M40 for flat slab and M25 for column.

   Other sefians may correct me if I am wrong.

Yours sincerely
Arunkumar

Dear Mr. Arun Kumar,

Thank you for your valuable reply.

My main concern was can we use higher grade for horizontal members and lower grade for vertical members.


Regards,
