## Calculate Quantity of Cement,Sand,Aggregate in Column

Hello civil engineers in this article we will teach how to calculate cement,sand and aggregate in column at grade of M20

How to compute the quantity for cement, sand and aggregate for a concrete column

This construction video is captured to show you how to estimate quantity for cement, sand and aggregate in a concrete column.

Here, the dimension given for front section of column is 300 mm x 300 mm

The height for gross section of the plan is 3 Meter.

Here, M20 grade concrete ratio is 1:1.5:3 and if you sum up, ratio will be 5.5

Therefore, volume of column that is represented as V = 0.27 m3 (meter cube). We get this volume from the specified 3 dimensions.

Now, it is required to convert wet volume into dry volume. Apply the following formula to do this :-

Wet Volume x 1.54 = 0.27 x 1.54 = 0.4158 m3

Therefore, Volume of cement = 1/5.5 x 0.4158 = 0.0756 m3

In order to convert the cement volume to bags, apply the following formula :-

0.0756/0.0347 = 2.17 bags of cement

Volume of sand = 1.5/5.5 x 0.4158 = 0.1134 m3
