Introduction of Cement Plastering:

• Cement plastering is the process in which the cement mortar is applied to the surface of the wall to protect it from the penetration of water and other aggressive environmental conditions.
• In this article, we will see how to calculate the amount of cement & sand required for plastering and how to calculate the cement sand quantity for brickwork.
• The cement mortar ratio which is generally used for the plastering depends upon the type of plastering work.
• There are various types of cement mortar ratio are used for different types of cement plaster design.
• The plastering ratio which is recommended for the plastering of the plane surface, the rough surface of the brick wall, and the rough surface of the concrete walls and ceilings are 1:6, 1:4 and 1:5, and 1:3 are used respectively.

How Many Cement Bags Per Square Metre for Plastering?

Step 1: Volume of Plaster.

Step 2: Dry Volume of Plaster.

Step 3: Volume of Cement in M3.

Step 4: Volume of Cement in Bags.

• The volume of one bag of cement is 0.0347 m3

Step 5: Volume of Cement in Kg.

• The density of cement is 1440 kg per m3
• There are 0.08 cement bag is required for the plastering work of one square metre.

How to Calculate the Cement Sand Quantity for Plastering?

How to Calculate Plastering Quantity?

How Much Cement in 1 Cubic Metre Brickwork?

• The size of the modular brick is 190 x 90 x 90 mm.
• Mortar Thickness is 10mm.
• Assume required brickwork volume is 1 cubic metre (m3).

How to Calculate Quantity of Cement Mortar in Brickwork and Plaster?

• The brickwork consists of bricks and cement mortar.
• So firstly we have to find the volume of bricks with mortar thickness and the volume of bricks alone.

Volume of Bricks with Mortar.

• Volume of 1 brick with mortar = 0.2 x 0.1 x 0.1 m
• Volume of 1 brick with mortar = 0.002 Cu.m. (m3)
• The Volume of brick with mortar = 0.002 Cu.m. (m3)

Volume of Bricks Without Mortar.

• Volume of 1 brick without mortar in mm = 190 x 90 x 90 mm
• Volume of bricks without mortar in m= 0.19 X 0.09 X0.09.
• Volume of 1 brick without mortar in cubic metre   =  0.001539 Cu.m. (m3)
• Volume of 500 bricks without mortar in cubic metre = 500 X 0.001539 Cu.m. (m3)
• Volume of bricks without mortar for 1 cubic metre= 0.7695 Cu.m. (m3)

How to Calculate Cement Consumption in Brickwork?

• Required Amount of Cement Mortar = 1 m3 – Volume of Bricks without Mortar
• Required Amount of Cement Mortar = 1 – 0.7695
• Required Amount of Cement mortar  = 0.2305 Cu.m.  (m3) (Wet Condition)

• Dry Volume of a Mortarr = Required Amount of Cement mortar x [(100 + 300) %]
• Dry Volume of a Mortar = 0.2305 m3 x 1.33
• Dry Volume of a Mortar = 0.306565 m3

• Required Amount Cement Quantity in Brickwork = Dry Volume of a Mortar x Cement Sand Ratio x Density of Cement 
• Required Amount Cement Quantity in Brickwork = 0.306565 x 1/7 x 1440 kg
• Required Amount Cement Quantity in Brickwork = 63 Kg
• Required Amount Cement Quantity in Brickwork = 63 kg/ 50 kg ( Cement Bag Weight)
• Required Amount Cement Quantity in Brickwork = 1.26 bags
• Required Amount of Sand = Dry Volume of a Mortar x Sand Cement Ratio
• Required Amount of Sand = 0.306565 x 6/7
• Required Amount of Sand = 0.26277 Cubic metre (m3)

• 500 Numbers of brick.
• 63 kg of cement.
• 263 m3 of sand.

How to Calculate the Cement Sand Quantity for Plastering?

1. Density of Cement = 1440 kg/m3.
2. Sand Density = 1450-1500 kg/m3.
3. Density of Aggregate = 1450-1550 kg/m3
4. How many KG in 1 bag of cement = 50kg.
5. Cement quantity in liters in 1 bag of cement = 34.7 litres.
6. 1 Bag of cement in cubic metres = 0.0347 cubic metre.
7. How many CFT (Cubic Feet)  = 1.226 Cu.Ft.
8. Numbers of Bags in 1 cubic metre cement = 28.8 Bags

How to Calculate the Cement Sand Quantity for Brickwork?

1. Standard Size of Brick = 190 x 90 x 90 (mm) Quality check of brick.
2. Mortar Thickness is = 10 mm.
3. Mortar quantity is 0.2305 (Wet Condition) we calculate Dry Value.
4. Volume = 0.306565x (1/7) = 0.0438.
5. Volume = 0.306565x (6/7) = 0.2627.

How to Calculate Quantity of Cement Mortar in Brickwork and Plaster?

• Standard Size of Brick = 190 x 90 x 90 (mm) Quality check of brick.
• Mortar Thickness is = 10 mm.
• Mortar quantity is 0.2305 (Wet Condition) we calculate Dry Value.
• Volume = 0.306565x (1/7) = 0.0438.
