Answer Posted / mohammed mohiddin
1. M20 mix stands for 1:2:4 proportion
2. 1 cm.m of M20 mix contains 1+2+4 = 7 parts, in which
1 part of cement, 2 part of fine aggt & 4 part of
Course aggt.
3. unit wt of plain concrete (without steel) = 2400 kg/m^3.
4. Now,
Cement = 1/7 X 2400 = 342.85 kg
Fine = 2/7 x 2400 = 685.71 kg
Course = 4/7 x 2400 = 1371.43 kg
This way any problems of these kind can be sorted out.
... Good Luck...
