@Kashif.

How we can determine the number of sample tests?

Vignesh said:   1 decade ago
For m50 what will be the ratio?

Kashif said:   1 decade ago
The general expression is 1:n:2n by volume where n is the number of sample test conducted.

For this firstly, you can understand the two term:

First term:- Nominal mix.
Second term:- Design mix.

M30-Depend on design mix (OR) M-30 = 1:1:1.

@Sneka, your assumption is wrong, for M-15 ,the ratio is 1:1.5:3 by yours way summation all 1+1.5+3 = 5.5.

M-5 1:5:10.
M-7.5 1:4:8.
M-10 1:3:6.
M-15 1:1.5:3.
M-20 1:2:4.
M-25 1:1:2.

M-5 1:5:10.
M-7.5 1:4:8.
M-10 1:3:6.
M-15 1:1.5:3.
M-20 1:2:4.
M-25 1:1:2.

All of the above grade are made by design mix method.

M10 mix was only used for foundation purpose. Because that having less compressive strength.

Baldev said:   1 decade ago
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.
