Finishing Air-Entrained Concrete

Used in many applications, air-entrained concrete uses a chemical admixture (or sometimes, air-entraining cement) to produce a system of small voids during the mixing process. These voids are stabilized by the air-entraining admixture and remain in the hardened concrete paste. The primary use of air-entraining concrete is for freeze-thaw ...

Chemical Admixtures

Air bubbles are generated during the agitation and mixing of the concrete. The air-entraining agents simply helps to stabilize these bubbles by the above action. Some common chemicals used as air entrainers are neutralized vinsol resin, derivatized pine rosin, and fatty acids (detergents).
