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:-

Tanmay Mandal says:

We require M20,M30 Mix design as per cement company wise 1) Ambuja Cement (2) Lafarge Cement (3) Altratech Cement (4) Ramco CEmnet (5) Binani Cement according to 43 grade & 53 grade OPC Cement
This is very Urgent.

Correct Ratio’s are given below

Grade 10 = 1:4:8
Grade 15 = 1:3:6
Grade 20 = 1:2:4
Grade 25 = 1:1.5:3
Grade 30 = 1:1:2

HAFEES.A.M
M10 =1:4:8
M15 = 1:3:6
M20 = 1:2:4
M25 = 1:1.5:3
M30 = 1:1:2

Mukesh says:

sir pls send me mix design for M30 concrete

kishore says:

sir can u pls tell me correct mix design propotion for M 10 to M 35 ratio sir….!!!!!!! there are two kinds of mix design ratio mentioned above….tell me which one 2 follow..!!!!???

Mohan Shah says:

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

sir i would be glad if i can get the mix ratio of M:35

megna salinas says:

m10=1 3 6, M15=1 2 4 ,m20=1 1.5 3 .m25=1 1 2

ramakrishna says:

how are you calculating m10 as 1:3:6 can you mail the formula

abdul qayyum aziz says:

what is highest strength concrete being produced in the world nowadays?

Rajendran says:

M7.5=1:4:8
M10=1:3:6
M15=1:2:4
M20=1:1.5:3
M25=1:1:2
These are nominal mix ( By volume)

nixon obuyu says:

M10…1:4:8
M15…1:3:6
M20…1:2:4
