How admixture work in concrete and different type of admixture and its uses.

Question

Accepted Answer

Admixtures are added to concrete to alter its properties or enhance its performance. They can improve workability, durability, and strength.

Admixtures are added to concrete during mixing to modify its properties.
Types of admixtures include water-reducing, air-entraining, accelerating, retarding, and plasticizers.
Water-reducing admixtures improve workability and reduce water content.
Air-entraining admixtures create small air bubbles in concrete to increase durability.
Accelerating admixtures speed up the setting time of concrete.
Retarding admixtures delay the setting time of concrete.
Plasticizers improve workability and reduce water content without affecting setting time.
Examples of admixtures include lignosulfonates, polycarboxylates, and calcium chloride.
