Mortar Calculation for Plastering work

- 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 much sand and cement do I need for plaster?

For wall plaster generally ratio we use = 1: 6 (1 part of cement and 6 part of sand). For Roof plaster mainly ratio we use = 1: 4 (1 part of cement and 4 part of sand). The thickness of plaster is between = 12 mm to 15 mm. Always use good quality cement (Different grades of cement) as well as good quality sand.

**How many bags of cement are required for 1 square Metre of plastering?**

Ans. 0.154 bags cement required per square metre for plastering in case of 20 thick plaster & cement sand ratio 1:4.

**What is the formula for plastering wall?**

Note: By considering dry density of sand = 1550 kg/m3….Strength of plastering/nominal mix:

Plaster type | Description |
---|---|

15mm | 15 MM cement plaster is required on the rough side of 9” and 4.5” wall. |

18mm | 18 MM thick cement plaster with neat cement slurry is required for making ‘Dado’ with the cement concrete flooring. |

## How do you calculate mortar?

How to Calculate the Amount of Mortar Mix Needed

- Find the area of your brick structure by multiplying length and width.
- Multiply the square footage by seven to estimate the number of bricks you use in your project.
- Divide the total number of bricks by 30 to estimate how many 60-pound bags of mortar mix you need.

### How do you calculate mortar quantity?

Mix Ratio 1:4

- Cement (bags) Cement = 1/5 x (volume of mortar) = 1/5 x 3.28. = 0.656 m3 (volume of 1 bag of cement = 0.035 m3) = 0.656/0.035. Cement = 18.74 bags = 19 bags.
- Sand (cu.ft) Sand = 4/5 x 3.28. Sand = 2.62 m3.

**How do you calculate amount of plaster?**

Calculation of quantity of material for 12 mm thick plaster of ratio 1: 6 (1 Cement:6 Sand) in the wall for 100 Sqm

- Quantity of Cement = 2/(1+6) × 1 (1 Ratio of cement)
- In Kg = 0.30 × 1440 (Density of cement = 1440 kg/m3)
- Quantity of Sand = 2/(1+6) × 6 (6 Ratio of sand)
- In Cubic Feet = 63.558 cft (1 Cum = 35.31 cft)

**How many square meters of plastering can 1 Mason a day?**

So one mason, 10/0.67 = 14.92 m2 plastering done in one day.

## How do you calculate cement for mortar?

Quantity of cement:-

- Quantity of Cement = (Dry Volume of mortar x Cement ratio) / (Sum of the ratio)
- Density of Cement = 1440 kg/m³
- 1 bag of cement contains 50 kg of cement.
- Cement : Sand :: 1:4.
- Quantity of Sand = Quantity of Cement x 4.
- 1 m³=35.3147 Cubic Feet (CFT)
- Density of sand = 1920 kg/m³
