### 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%

Output of mix is considered as 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 cement = 50 kg.

Therefore volume of 1 bag 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.

Drawing

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.

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…

Please reply some one who knows this

How to calculate cemant bages … plzz tell me

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.
