how to decide cement quantity in 1 m3 concrete

Answer Posted / mehar

For example take m15 grade of concrete.. It's ratio 1:2:4
1+2+4 =7
So cement having 1 m3 wet volume.
But dry vol= wet volume x1. 54 m3(45-55 % of dry volume)
Wt of cement =(1x1.54x1440) /7 = 312kg
Convert to bags = 312/50 = 6.25 bags
So for 1m3 of concrete work of m15 grade comcrete nearly 6.5 bags of cement if required..
