How to calculate the amount of cement & sand required for
plastering work with ratio 1:4 please give me an answer with
detailed step.
Answer Posted / rajarshi basu
Area to be plastered=100 m^2
Thickness of plaster=12mm=(12/1000)m= 0.012m
Volume of mortar required= 100 x 0.012= 1.20 m^3
Add 20% extra mortar for filling joint,depressions and
wastage.
Volume of the mortar= [0.20 X 1.20]+ 1.20=1.44 m^3
[Wet Volume]
Increase further by One-third of the volume to get Dry
volume
Quantity becomes= [(1/3) X 1.44]+ 1.44=1.92 m^3
Summation of proportion=1+4=5
For 12mm plastering in 1:4 cement :sand mortar mix:
1)Cement required= 1.92/5= 0.384 cu. m
No. of bags of cement= 0.384/0.0347=11.06 bags
>> 11 bags(say)
Cement used =11 x 50= 550 kg
2)Sand required= [1.92 x (4/5)]= 1.536 cu. m
Important note:
[Weight of 1 bag of cement= 50 kg
Cement should be always measured by weight to avoid
variation.
One 50 kg bag of cement weighs 1440 kg/cu. m
Volume of 1 bag of cement= 50/1440=0.0347 cu. m ]
Therefore to convert Cu. m into No of bags of 50 kg
cement,just divide the volume of cement by 0.0347
Hope u have understood!!!!
