Concrete Mix Design Calculations

The concrete mix design available on this site are for reference purpose only. Actual site conditions vary and thus this should be adjusted as per the location and other factors. These are just to show you how to calculate and we are thankful to all the members who have emailed us these mix designs so that these could be shared with civil engineers worldwide.

If you also have any mix design and want to share it with us, just comment on this post and we will be in touch with you.

Here is the summary of links of all the mix designs we have till date:-
