During construction of house it is necessary to know, how to calculate the quantity of plaster with Material. The construction owner of house is confused about the above knowledge Now here steps of calculation for reference.
Building / house owner decide 20 mm thick plaster required for external wall of building/house
Consider 50 M length of wall and 3 M height of building wall and cement plaster ratio is 1:5 (cement to sand )
Quantity of plaster =50 X 3 =150 Sq.mt
Calculate wet volume of plaster =150.00 X (20/1000) =3.00 Cu.mt
Increase 30% dry volume to wet volume = 3.00+(3.00 X 30% )= 3.90 Cu.mt
Calculate the Material quantity i.e cement and sand
Cement Quantity = (3.90 X 1 ) / (1+5) = 0.65 Cu.mt
volume of 50 kg cement bag = 0.035 Cu.mt
Number of 50 kg Cement bag = 0.65/ 0.035 = 18.57 Cement bag
Sand Quantity = (3.90 X 5 ) / (1+5) = 3.25 Cu.mt = (3.25/2.83) = 1.14 Brass
1 Brass sand =2.83 Cu.mt
Summery- 20mm plastering for 50 M length and 3 M Height wall 18.50 number of cement bag and 1.14 Brass sand Require
