*How to Calculate the Total Bags of Cement for a Particular Volume of Concrete simplified version*

As an individual that wants to build a house or any other structural units, you must know the amount of cement require for a particular volume of concrete, knowing this will prevent contractors or bricklayers from extorting you. I will explain to you how to calculate the amount of cement require for any volume of concrete.

Amount of cement = V * k
Where V= volume of concrete
K= Multiplication constant
And the Multiplication factor can be gotten from the picture attached, by checking the mix design that you are using and picking the constant K.

Example. A concrete of 4 meters long, 2 meters tall and 0.225 width of 0.225 meters. Using M15 (1:2:4).

Solution
Amount of cement = V * k
V= length * height *width
= 4 * 2 * 0.225 = 1.8 m3
K= 6.336 ( from the table in the picture)

Bags of Cement require = 1.8 * 6.336 = 11.4048 bags.
