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.

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.

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.

Grade means types of aggregate whether it is fine or coarse. According to the grade the aggregate shape is depend.
For: M5-1:5:10 M10-1:4:8 M15-1:3:6 M20-1:2:4 M25-1:1. 5:3 M30-1:1:1.
For: M5-1:5:10 M10-1:4:8 M15-1:3:6 M20-1:2:4 M25-1:1. 5:3 M30-1:1:1.

M10 mix is never used in column, slabs or beams. It is a layer of cement concrete separating the earth to the main concrete in foundation or you can say it is only used in foundation.

By comparing M10 and M15 we can see that for more strength ratio is decreasing. Just remember M10 then M20/M15 and all other mix become easy to understand.
