# Concrete Mix Design Calculations

Posted in Mix Design |  Email This Post |

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:-

Mix Design For M20 Grade Of Concrete

Mix Design For M35 Grade Of Concrete

Mix Design For M40 Grade Of Concrete

Mix Design For M50 Grade Of Concrete

Mix Design For M60 Grade Of Concrete

In case you want the complete theory of Mix Design, Go here What is Concrete Mix Design

We will add more soon. You can help us do this fast, just email us any mix design you have.

Hello.. satheesh….
Sorry you are totally incorrect.. correct ratio’s given below..

M10 =1:4:8
M15 = 1:3:6
M20 = 1:2:4
M25 = 1:1.5:3
M30 = 1:1:2

• V R Puli July 16, 2011 at 2:32 am

Hai ashwini, whatever mentioned by you are incorrect. M15= 1:2:4. M20=1:1.5:3 M25=1:1:2

Could you please send me the mix ratio for concrete grade 10, 15, 20, 25, 30, 35 and 40.

Also if i could have a chart showing tolerance for meeting the strength at day 7, 14, 21 and 28.

Thank you, as i look forward to your urgent response.

faithfully yours
