The discussion confirms this standard and provides a general table of common nominal mix ratios for different grades of concrete (M-grades are specified by their characteristic compressive strength in N/mm²).

The discussion page focuses on the M10 grade of concrete, establishing that its nominal mix proportion is approximated as 1:3:6 (Cement: Fine Aggregate: Coarse Aggregate).

This designation is based on IS 456-2000, where 'M' stands for 'Mix' and the number '10' represents the concrete's specified minimum 28-day cube compressive strength of 10 N/mm^².

@All.

This discussion provides a straightforward confirmation of the standard nominal mix ratio for M10 grade concrete, referencing the IS code for validation and clarifying the parts of the ratio.

The thread serves as a good, quick reference for students and professionals seeking to memorise these essential concrete mix proportions used in construction.

According to me, the Correct ratio is 1:5:10.

If, for M10 rade 1+3+6=10.
Then for M20, 1+2+4=7 its not 20 then how its possible.

These all are nominal mix,

M5= 1:5:10
M7.5= 1:4:8
M10 = 1:3:6
M15 = 1:2:4
M20 = 1:1.5:3
M25 = 1:1:2
M30 = 1:0.75:1.5
M35 = 1:0.5:1
M40 = 1:0.25:0.5

For the Design mix, the ratio will change depending upon the location, soil conditions...etc.

M5 = 1:5:10.
M7.5 = 1:4:8.
M 10 = 1:3:6.
M15 = 1:2:4.
M 20 = 1:1.5:3.
M25 = 1:1:2.
M30 = 1:0.75:1.5.
M 35 = 1:0.5:1.

M5 - 1: 5: 10.
M7. 5 - 1: 4: 8.
M10 - 1: 3: 6.
M20 - 1: 1.5: 3.
M25 - 1: 1: 2.

@Sisir mal.

Please tell me from where we get the ratio M5 to M25 by nominal mix?
