Bindemittel: Cements and Mortars

Bindemittel, often referred to as adhesives or construction materials, play a crucial role in the production of various products, including fiberboards and concrete. In the context of construction, binders, such as cements and mortars, are essential for holding materials like concrete and bricks together. This article focuses on the properties and characteristics of cements and mortars as binders.

Cements

Cement is a fine powder made from raw materials such as limestone, clay, and shale. When mixed with water, it forms a paste, which then hardens over time. There are several types of cement, including Portland cement, which is the most commonly used type in construction.

Properties

Cement has several properties that make it suitable for use as a binder. These include:

• Water resistance: Cement is resistant to water and moisture, making it suitable for use in wet environments.
• Compressive strength: Cement has a high compressive strength, which means it can withstand heavy loads without breaking.
• Durability: Cement is durable and can last for many years without degrading.

Portland Cement

Portland cement is a type of cement that is named after the English town of Portland, where it was first produced. It is made from a mixture of limestone and clay, which are heated in a kiln to a high temperature. The resulting product is then ground into a fine powder. Portland cement is commonly used in the production of concrete, as it provides the binding agent that holds the other materials together.

Mortars

Mortar is a mixture of cement, sand, and water. It is used to bind bricks or other masonry materials together. Mortar is essential for holding masonry structures together and providing a smooth surface for plastering or painting.

Properties

Mortar has several properties that make it suitable for use as a binder in construction:

• Workability: Mortar is easy to mix and spread, which makes it suitable for use in masonry work.
• Strength: Mortar has a high compressive strength, which means it can withstand heavy loads without breaking.
• Durability: Mortar is durable and can last for many years without degrading.

Mortars with Alternative Binders

In recent years, there has been a growing interest in using alternative binders in mortars, such as natural cements and mineral admixtures. These alternative binders can improve the properties of mortars, such as reducing their environmental impact or increasing their resistance to chemicals.

For example, researchers have studied the use of Portland cement-based mortars with alternative binders, such as rice husk ash and fly ash. These alternative binders can improve the strength and durability of the mortars, making them suitable for use in different applications.

Conclusion

Bindemittel, such as cements and mortars, play a vital role in the production of various products and the construction of buildings. Their properties, such as water resistance, compressive strength, and durability, make them suitable for use as binders. In recent years, there has been a growing interest in using alternative binders in mortars, which can improve their properties and reduce their environmental impact.
