What is the reason of adding of admixture

Question

Accepted Answer

Admixtures are added to improve the properties of concrete, such as workability, strength, durability, and resistance to chemicals.

Admixtures can improve the workability of concrete by reducing water content or increasing flowability.
Admixtures can enhance the strength and durability of concrete by reducing permeability, increasing compressive strength, or improving resistance to freeze-thaw cycles.
Admixtures can also improve the resistance of concrete to chemicals, such as corrosion inhibitors for reinforced concrete structures.
Admixtures can help achieve specific properties in concrete, such as faster setting times or reduced shrinkage.
Examples of admixtures include water reducers, air-entraining agents, accelerators, retarders, and superplasticizers.

Accepted Answer

Admixture is increased of workability, and water controller for strength increases
