# 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/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)**
