Procedure To Calculate Cement Bags In 1 Cubic Meter
Let us consider the nominal mix is 1:2:4
Loss of cement is considered as 2%
The output of the mix is considered to 67%
To achieve 1 cum output, we need 1/0.67 = 1.49 say 1.50 cum dry mix.
Now add the wastage of 2%, i.e (1.50 + 0.02) = 1.52 cum.
Volume of cement = (cement/cement+sand+aggregate) × Total material
=(1/1+2+4) × 1.52
=0.2171 cum
As we know, the density of cement is 1440 kg/cum and
Weight of 1 bag of cement = 50 kg.
Therefore the volume of 1 bag of cement = 50/1440
=0.0347 cum.
∴ No. of cement bags required in 1 cubic meter = 0.2171/0.0347
= 6.25 bags.
Note: You can use the same formula for calculating cement for other nominal mixes.

Good knowledge. Thanks.
Good work.

Very good knowledge
If Mix 1:2:4 then volume of cement =cement/cement+sand+Aggregate =(1/1+2+4)×1.52 sand 2 time of cement Qty
Hi
why the volume of cement is divided by cement again(cement/cement)?
This is because while dealing with ratios, a constituent component is divided by the total to get its representative fraction and then multiplied by the amout to get the actual quantity.
I will love know more about calculation in civil engr
how the f did he get 0.2171 cum? I am so confused 😀
M15 = 1:2:4
Sum of the ratio = 1+2+4=7
Total material =1.52
Now
1.52*(1/7)=0.2171
Here 1 is the ratio of cement
V.g far, great work, keep up, Thanks…
I will appreciate if how to calculates for the volume of sand and the aggregates too is also illustrated as a topic. Thanks
Please reply some one who knows this
Could u kindly mail me about the design mix of m40 grade concrete.

1:1.5:3 mix concrete 1cum me cement ki quantity ?
Cement ki quantity=(1.54/1+1.5+3)*1
=.28cum
Bag of cement= .28*1440
= 403.2 (8.0 64)
Sir KyA ye right answer hai.
No, this is wrong calculation. Cement required For 1 cum (1:1.5:3) 8 bags .
This is great, thank you sir.
1.52/7=0.2171428*1440=312.7/50=6.25 bags. another way of doing it.
/7=1:2:4 Ratio
1.52/7=0.2171428*1440=312.7/50=6.25 bags of cement.
1.52/7=1:2:4 Ratio.
Why 67% output & 2% wastage and what happen to the remaining 31%?
