Concrete admixtures are used to improve the behavior of concrete under various conditions and are of two main types. These are chemical and mineral additives.
• CHEMICAL ADDITIVES
Chemical additives reduce the construction cost, change the properties of the hardened concrete, ensure the quality of the concrete during mixing transport placement curing, and overcome some emergencies during concrete operations.
Chemical additives are used to improve the quality of concrete during mixing, transport, placing and curing. They fall into the following categories:
air entrainers
water reducers
set delay
Set accelerators
Super plasticizers
•MINERAL ADDITIVES
Mineral additives make mixtures more economical, reduce permeability, increase strength and affect other concrete properties.
Water reducing additives
retardant additives
accelerator additives
