Get some useful construction tips for finding out the quantity of plaster for a wall. Here, the length of the wall is taken as 6 meter, height is taken as 3 meter and thickness is taken as 12 mm = 0.012 meter.
To work out the quantity of plaster, the following formula is used :-
Volume of plaster = L x h x thickness = 6 x 3 x 0.012 = 0.216 m3
This is the wet volume and it should be converted to dry volume with the following formula :-
Dry volume = Wet volume x 1.27 = 0.216 x 1.27 = 0.274 m3
Now the ratio of plaster is taken as 1 : 4 (1 = cement and 4 = sand) By summing up we get 5
Therefore, volume of cement = 1/5 x dry volume of plaster = 1/5 x 0.274 = 0.054 m3
In order to convert this volume into bags of cement i.e how many bags are necessary for this plaster, apply the following formula :-
0.054/0.035 (here 0.035 denotes cement bag volume in meter cube) = 1.56 No. of bags
