DIRECT ESTIMATION METHOD : =
M20 (1:1.5:3) for 10 m^3
1. cement content = 15.2 \ (1+1.5+3)
= 2.763 cum
= 82 bags of 50 kg
2. water = 2.763 cum * 1.5
3. ca + fa = 2.763 * 3 cum
* here 15.2 is a standard value worked out from experiments.
so for 10 m^3 u can divide the sum of ratio by 15.2 to get
amount of cement directly...
* 50 kg of cement (1 bag) = (1/30) m^3 so = 0.034 cum
2.763cum / 0.034 cum = 82 bags
similarly u can work it out for
M25 1:1:2
m15 1:2:4
m10 1:3:6
