What are the roles of additive?

Construction additives play several roles in construction, including:

1. Enhancing properties: Additives can improve the properties of concrete, such as strength, durability, workability, and setting time.

2. Modifying behavior: Additives can modify the behavior of concrete, such as reducing shrinkage, increasing flowability, or improving adhesion.

3. Reducing costs: Additives can reduce costs by replacing expensive materials or reducing the amount of cement needed.

4. Improving aesthetics: Additives can enhance the appearance of concrete, such as by adding color or texture.

5. Meeting specific requirements: Additives can be used to meet specific requirements, such as fire resistance, water resistance, or freeze-thaw resistance.
