# Introduction of Cement Consumption for Plastering of Internal Brick Wall

In many places, especially in developing countries, the use of cement for plastering of internal brick walls is a common practice. The cement is usually mixed with sand and water to form a paste, which is then applied to the bricks. The advantages of using cement for this purpose are that it is cheap and easy to obtain, and it dries quickly. However, there are also some disadvantages, such as the fact that cement is a very strong acid and can damage the bricks if not used correctly.

## Cement Consumption in Plaster 1:4 for 1m2 Area

• The recommended cement consumption for plastering a 1:4 ratio with a thickness of 12mm is approximately 25-30kg/m2
• This would mean that for an area of 1m2, you would need approximately 25-30kg of cement.

## Cement Consumption in Plaster 1:4 for 1m2 External Brick Wall

• Assuming a 1:4 plaster mix on a exterior brick wall, would be using 500kg of cement per square metre
• This is a high end estimate bulking the cement up to account for poor workmanship
• A more reasonable consumption estimate for a 1:4 plaster mix on a brick wall would be 300-400kg per square metre.

## Calculate Cement Consumption for Internal Plastering for 1m2 Area

• Assuming a thickness of 12mm for the internal plastering, the cement consumption for 1m2 area would be:

1/0.012 = 83.33 kg/m2

Therefore, the cement consumption for internal plastering for 1m2 area would be 83.33 kg.

## Cement Consumption for Plastering of Internal Brick Wall

• Cement consumption for plastering of an internal brick wall is calculated at approximately 7 bags per square metre.

## Conclusion

The number of cement bags required for 100 sq. ft. plastering of internal brick wall of 12″ thickness is 7.6 bags. The cost of cement for plastering of 100 sq. ft. internal brick wall of 12″ thickness is Rs. 556. The total quantity of sand required is approximately 30% more than the volume of cement. The rest of the materials like coarse aggregates, water etc. are required in small quantities and their cost is insignificant as compared to cement and sand.
