Difference Between Lime & Cement Plaster:
1. Introduction
Plaster is a lean mortar used for decorative and protective purposes for coating of the wall, design finish, protection against weathering agents, etc.
It is composed of binding material ( cement or lime) with sand or coarse aggregate and water.
2. Types of Plaster
a. Cement plaster
The type of plaster which uses cement(generally portland cement) as the main binding materials along with sand and water mixed in definite proportion for a different purpose.
b. Lime plaster
The plaster that contains lime as binding material along with sand and water is known as lime plaster. It is the oldest form of plaster mostly used before the 1900s.
3. Difference Between Cement and Lime Plaster
The difference between cement plaster and lime plaster is given below;
| Lime Plaster | Cement Plaster |
| It is more workable. | It is less workable. |
| It hardens slowly. | It hardens quickly. |
| It provides a good thermal insulator | It is not so good a thermal insulator(i.e, cause condensation and mold problems). |
| It can be recycled. | It is not reusable but can be used as a landfill. |
| Curing time is less. | Curing time is more (i.e 28 days). |
| It sets slowly. | It sets quickly. |
4. Difference Between Lime and Cement
| S.N. | Lime | Cement |
| 1 | It is less prone to cracking. | It is more prone to cracking. |
| 2 | It is less brittle. | It is more brittle. |
| 3 | It is white or greyish in colour. | It is greenish-grey in colour. |
| 4 | It slakes when wetted with water. | It does not slake when wetted with water. |
| 5 | It sets slowly when mixed with water. | It sets rapidly when mixed with water. |
| 6 | It delays the construction. | No delay in construction as compared to lime. |
| 7 | It possesses less strength. | It possesses high strength. |
| 8 | It allows vapour to pass through. | It does not allow vapour to escape. |
| 9 | It helps to reduce moisture and improve the environment of the home. | It can absorb water causing moisture to accumulate especially in the basement. |
| 10 | Its production does not cause global warming like cement. | Its production greatly leads to global warming. |
| 11 | It has less embodied energy than cement. | It has embodied energy. |
| 12 | It is possible to manufacture lime on a small scale. | It is impossible to manufacture cement on a small scale. |
| 13 | Its binding strength is less compared to cement. | It has strong binding properties than lime. |
| 14 | Lime hardens slowly when mixed in producing mortar. | The cement hardens quickly when mixed in a mortar. |
| 15 | It cannot be used for important and heavy engineering structures. | It can be used for important and heavy engineering structures. |
| 16 | It is cheaper. | It is expensive. |
5.Conclusion
In terms of cost and environment; lime is best. It doesn’t lead to the production of harmful gases and contributes to controlling global warming.
It is also possible to produce lime in small quantities. Hence, it is also economical to produce.
In terms of strength, durability and other qualities; cement is best because it poses high strength and good binding.
