# How to Calculate Cement, Sand Quantity for Plastering?

## Mortar Calculation for Plastering work

__Point Should Be Know Before Estimating __

__Point Should Be Know Before Estimating__

**Density of Cement ** = 1440 kg/m3

**Sand Density ** = 1450-1500 kg/m3

**Density of Aggregate **= 1450-1550 kg/m^{3}

**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

**Specific gravity of cement** = 3.15

**Grade of cement **= 33, 43, 53

**Where** 33, 43, 53 compressive strength of cement in N/mm^{2}

—————————————————————————————————————————————————————–

**Area of brick wall for plaster** = 3m 3m =9m^{2}

Plaster Thickness = 12mm (Outer-20mm, Inner 12mm)

Volume of mortar = 9m^{2} x 0.012m = 0.108m^{3}

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 m^{3}

**Cement**= (1/7) x 0.1458 = 0.0208 m^{3 }

*Density of Cement is 1440/m ^{3}*

= 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 = 0.124m^{3}

*Density of Sand is 1450/m ^{3}*

= 0.0208 x 1450 = **181.2 kg**

Now we find how many CFT (Cubic feet) Required

* As we know that 1m ^{3} = 35.31 CFT*

= 0.124*35.31

** = 4.37 CFT (Cubic Feet)**

CALCULATOR FOR STEEL QTY

good

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?

Please Specify 1.35

I want to know how to calculate the plasterwork of a round shape, repairing work type?

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

chec sand volume.it should be 0.124.not 0.0208
