Air entrainment is the basically creation of small air bubbles in concrete. The bubbles are introduced into the concrete by the addition of an air entraining agent to the mix. The air bubbles are created during mixing of the flowable concrete, and most of them survive to be part of the hardened concrete. The primary purpose of air entrainment is to increase the durability of the hardened concrete, especially in climates subject to freeze-thaw; the secondary purpose is to increase workability of the concrete.
Our 3C AIR is used as an air entraining agent for mortars, plasters and grouts based on cement, gypsum or lime. It is rapidly soluble, enables faster wetting of the solid particles of the dry admixture and the build-up of micro foam in a short time. The performance of this air entrainer is superior to traditional air – entrainers, as it is twice as efficient in producing a controllable, strong and stable micro foam.
