How to Calculate Cement, Sand Quantity for Plastering?
Mortar Calculation for Plastering work
Point Should Be Know Before Estimating
Density of Cement = 1440 kg/m3
Sand Density = 1450-1500 kg/m3
Density of Aggregate = 1450-1550 kg/m3
How many KG in 1 bag of cement = 50kg
Cement quantity in litres in 1 bag of cement = 34.7 litres
1 Bag of cement in cubic metres = 0.0347 cubic meter
How many CFT (Cubic Feet) = 1.226 CFT
Numbers of Bags in 1 cubic metre cement = 28.8 Bags
The specific gravity of cement = 3.15
Grade of cement = 33, 43, 53
Where 33, 43, 53 compressive strength of cement in N/mm2
—————————————————————————————————————————————————————–
Area of brick wall for plaster = 3m 3m =9m2
Plaster Thickness = 12mm (Outer-20mm, Inner 12mm)
Volume of mortar = 9m2 x 0.012m = 0.108m3
Ratio for Plaster Taken is = 1 : 6
Sum of ratio is = 7
Calculation for Cement Volume
Dry Volume of Mortar = 0.108 x 1.35 = 0.1458 m3
Cement= (1/7) x 0.1458 = 0.0208 m3
Density of Cement is 1440/m3
= 0.0208 x 1440 = 29.99 kg
We know each bag of cement is 50 kg
= (29.99/50) = 0.599 Bags
Calculation for Sand Volume
Sand = (6/7) x 0.1458 = 0.124m3
The density of Sand is 1450/m3
= 0.0208 x 1450 = 181.2 kg
Now we find how many CFT (Cubic feet) Required
As we know that 1m3 = 35.31 CFT
= 0.124*35.31
= 4.37 CFT (Cubic Feet)

CALCULATOR FOR STEEL QTY
good
Nice one i really learn something crucial here..
excellent, sir
awesome
thank you
The calculation is amazing; it quiet comprehensible, I really appreciate. Thanks.
How to calculate the steel? Steel calculation formula =( d×d)/164 . Example suppose d= 8mm , sol = 64/164= 0.392 . Any doubts please contact
Calculation for steel
Unit weight = d^2/162
d = dia of bar
And total qnty = Nxd^2/162xL
L= length of bar
N=nos of bar
For steel calculation length of bar and shape of bar bar bending schedule knowledge
What is 164
Why multiplying 1.35 in dry volume calculation
Author, can you please answer how you got 1.35?
How much cement bags will be used for 20 cum plaster area
Download my Excel sheet
Please Specify 1.35
I want to know how to calculate the plasterwork of a round shape, repairing work type?
Just put, Area of circle
You have explained it very easily.
Step by step, Materials volume calculations and how to convert volume requirements to weight.
Thanks for everything
sand calculation wrong ( 01.24*1450) you mentioned ( 0.0208*1450)
0.124*1450
Why 1450, cement density is 1440
How to calculate primer/paint/putty requirement for brick walls
chec sand volume.it should be 0.124.not 0.0208
Love this calculations
There’s wrong in the last part of this calculation that’s instead of putting 0.124cubic meter of sand
you put 0.0208cubic meter which is the one of cement
Dear, Plaster Area, Calculation is good. Kindly Note that you have not considered the Wastage Factor, which is normally 10 %. Thank You.
Yes, I will update
Please specify 1.35?
we always calculate material quantity in dry formate so we take 34 % more than wet volume,
This is a great tutorial! I have been trying to calculate the cement and sand quantity for plastering for a while now and this has been a great help!
