What is the cementing material? And what types?

Cementing material is a substance used to bind or glue other materials together to form a solid mass. In construction, it is used to bind building blocks and create structures. There are several types of cementing materials available for use in construction, including:

1. Portland Cement: This is the most common type of cement used in construction. It is made by heating limestone and clay in a kiln to form clinker, which is then ground into a fine powder. Portland cement is used in a wide range of applications, including building foundations, walls, and floors.
2. Hydraulic Cement: This type of cement hardens when it comes into contact with water. It is used in applications where a strong, quick-setting cement is needed, such as in the construction of dams, bridges, and tunnels.
3. Lime: Lime is a type of cementing material that has been used for thousands of years. It is made by heating limestone to a high temperature to produce quicklime, which is then mixed with water to create hydrated lime. Lime is used in applications where a breathable, flexible cement is needed, such as in the construction of historic buildings and structures.
4. Gypsum: Gypsum is a type of cementing material that is made by heating gypsum rock to a high temperature and then grinding it into a fine powder. It is used in applications where a lightweight, fire-resistant cement is needed, such as in the construction of interior walls and ceilings.
5. Pozzolanic Cement: This type of cement is made by mixing pozzolanic materials (such as volcanic ash) with lime or Portland cement. Pozzolanic cement is used in applications where a cement with improved durability and resistance to chemical attack is needed.
