IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2.
The mixes of grades M10, M15, M20 and M25 correspond approximately to the mix proportions (1:3:6), (1:2:4), (1:1.5:3) and (1:1:2) respectively.

@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.

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.

We can also calculate the mix proportion of the aggregate by;
Dividing the no. of 30 into the no. of grade for example 10 ÷ 30=1 ÷ 3 it means the first no.
Is the quantity of cement(1) and second is fine aggregate (3) and third is coarse aggregate which is just double of the fine aggregate;
1 + 3 + 6 = 10.

Hello friends please tell me some material name by use of which we can increase the performance of concrete except admixture like silica fume, or some other chemical admixture.
Please if someone have any idea then please inbox me. Please help me try to give some innovative ideas.

Please tell me what is the calculation of find the grade of concrete. I know only the means of m10 10kn /mm2 strength but I don't know in which use the ratio in mix.
So please help me and send me mail the method of calculation in mixing ratio in all grade of concrete thnks.

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

Grade means characteristics strength of concrete after 28 days.
For example M-10
M represent mix &10 is the compressive strength of concrete after 28 days.
Characteristics strength means the expected result of the cube should not below 5%.

As per standard concrete mix design, the following mix are considered.
For M20 Grade - 1:1.5:3.
M15 Grade - 1:2:4.
M10 Grade - 1:3:6.
M7.5 Grade - 1:4:8.
M5 Grade - 1:5:10.
For M20 Grade - 1:1.5:3.
M15 Grade - 1:2:4.
M10 Grade - 1:3:6.
M7.5 Grade - 1:4:8.
M5 Grade - 1:5:10.

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).
