Air Entraining Admixtire Perma Plast AEA is a high performance, chloride-free water reducing cum air entraining agent for mortars, concrete and lightweight aggregate mixes. The introduction of Perma Plast AEA brings about entrainment of innumerable microscopic air bubbles of suitable size and spacing evenly distributed throughout the matrix. Perma Plast AEA lowers the surface tension of the mixing water. As a result, there is considerable reduction in the amount of mixing water required. The plasticizing nature of air entrainment assists in producing a dense, uniform close textured surface free gravel nests and honey combing. Perma Plast AEA that we manufacture, export and supply is compatible with all types of cements, sands and avoids Efflorescence and bleed in concrete.
