Air Entraining Admixtures (AEA™) is a highly effective liquid additive designed specifically to create concrete air entrainment. Extensive research on concrete durability has demonstrated that incorporating Air Entraining Admixtures significantly enhances the material’s resistance to the damaging effects of freeze-thaw cycles. In addition, these admixtures are specifically formulated to enhance the concrete’s surface resistance against chemical deicers, preventing surface peeling and deterioration.
Introducing small and uniform air bubbles throughout the concrete mixture, AEA™ helps improve concrete structures’ overall performance and longevity. It provides enhanced protection against the expansion and contraction caused by repeated freezing and thawing cycles, which can lead to cracking and structural damage. Furthermore, the admixture’s unique formulation offers superior resistance to the corrosive effects of chemical deicers commonly used on roads and other infrastructure.
AEA™ is a versatile solution suitable for various concrete applications, including concrete roads, bridge slabs, tables, and other projects exposed to water and demanding environmental conditions. With its high-quality composition and proven effectiveness, AEA™ offers exceptional reliability and durability in all concrete mixing projects.
By incorporating AEA™ Air Entraining Admixtures into your concrete formulations, you can ensure long-lasting performance, improved durability, and enhanced resistance against freeze-thaw cycles and chemical deicers, ultimately extending the lifespan of your concrete structures.

Air entraining admixtures (AEA™ code) are chemical additives for concrete that produce small and uniform air bubbles within the mixture. These admixtures are highly recommended for concretes that will be exposed to water, freeze-thaw cycles, and de-icing materials. They are commonly used in various applications, such as concrete roads, tables, and bridge slabs. Afzir concrete Air entraining admixture is renowned for its exceptional quality and can be utilized in all types of concrete mixing projects. According to the American Concrete Association’s report, Air entraining admixtures are defined as additives that induce the formation of microscopic air bubbles in concrete, mortar, and cement paste during the mixing process. These materials generate very small air bubbles that are evenly distributed throughout the volume of the concrete or mortar, and they should remain in place after the hardening of the material.

Frequently asked questions
Additives that cause the development of a system of microscopic air bubbles in concrete, mortar and cement paste during mixing.
According to the research conducted on the durability of concrete, the use of air entraining admixtures increases the durability of concrete against the thawing-freezing cycle.
Because more air has entered the concrete, the concrete will gain less weight, which is one of the good things for concrete.
In the cold seasons of the year when freezing is a normal phenomenon, water penetrates into concrete holes and freezes; Because water (up to -4 degrees Celsius) increases in volume in the ice state, cracks appear on the surface of the concrete, which are caused by the lack of compressive strength of the concrete against the increase in volume, which gradually leads to the failure of the concrete. This harmful phenomenon is called the thawing-freezing cycle.
