Methods used To Calculate Plastering Material Quantity

The term PLASTERING is used to describe the MORTAR that is used to cover the uneven surface of the wall and ceiling.

MORTAR

Before going for the calculation here is some important notes used in plastering calculation

There is two methods of the calculating quantity of cement, sand & water for plastering which are 

1)  Empirical method

2)  Dry loose bulk density method 

In these two methods, some differences can be seen between 100-500 g per square meter. This dry loose bulk density method is a more accurate method than the empirical method. The empirical method may vary based on the value of the voids on the volume of dry products (what we are saying is 1.27 factor may vary from brand to brand of the product)

LCETED TRIVIA

Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. When water is poured in cement and aggregate mixture the volume of the dry mixture is reduced to some extent. The mix

FOR PLASTERING

Percentage of voids due to fine aggregate = 27 %

Quantity of concrete is calculated from drawings. From there we obtain wet volume of concrete. So to calculate the quantity of raw material we need to convert wet volume to dry volume.

Therefore,

Dry volume = Wet volume + 54 % (Wet volume)

So, 1.27 is conversion factor of wet volume to dry volume of concrete.

Now take look on the calculations

Now you have an idea of calculating quantity for plastering by two methods. In these two methods, you can find some differences between the quantity which will not affect your material order
