how do we calculate quantity of cement , sand and
aggregates in 1 m3 of M30 grade concrete ?
Answer Posted / rajarshi basu
The approach by Sjtbehera is totally correct but has some
little silly mistakes...I have tried to give a rectified
solution.
In the case M30 design mix, the quantities of cement,sand
and aggregates cannot be calculated as it is a variable
quantity.It depends upon the Mix designer how much quantity
of cement,sand and aggregates he will employ.His only
intention would be to design a mix whose specified
characteristic compressive strength at 28 days=30 N/sq.mm
But in case of nominal mix we can use 1:1:2
Let us consider a volume of 10 cu. m (Wet concrete)
It is difficult to access exactly the amount of each
material required to produce 10 cu m of wet concrete when
deposited in place.
Hence to convert the wet volume into dry volume,
Increase by 54 % to account for shrinkage and wastage
Thus it becomes=15.4 cu. m (Variable upto 15.70)
Calculating cement, sand and aggregates in the mix:
Total summation of proportion=1+1+2=4
Cement = 15.4/4= 3.85 cu. m =3.85/0.0347=110 bags
Sand=15.4/4=3.85 cu. m
Aggregates(20mm to 6mm)=15.4 x (2/4)=7.70 cum
Hope u have understood and the mistake is clarified!!!
