Calcium hydroxide, also known as slaked lime or hydrated lime, is a chemical compound that is commonly used in construction for a variety of applications. Here are some common uses of calcium hydroxide in construction:
- Mortar: Calcium hydroxide is used in the production of mortar, a mixture of cement, sand, and water used to hold bricks or other building materials together. It is added to the mixture to improve workability, increase plasticity, and prevent cracking.
- Plaster: Calcium hydroxide is used in the production of plaster, a mixture of lime, sand, and water used to coat walls and ceilings. It is added to the mixture to improve the adhesion of the plaster to the surface, prevent cracking, and increase its resistance to water.
- Soil Stabilization: Calcium hydroxide is used to stabilize soils in construction projects. It is added to the soil to increase its strength and stability, improve its load-bearing capacity, and reduce its susceptibility to erosion.
- Concrete: Calcium hydroxide is used in the production of concrete as a chemical admixture to improve its workability, set time, and strength. It is also used to reduce the amount of water needed in the mixture, which can improve the strength of the final product.
- Asphalt: Calcium hydroxide is used in the production of asphalt as a chemical admixture to improve its workability, durability, and resistance to cracking. It is added to the mixture to improve its performance in extreme weather conditions and increase its lifespan.
