Water Reducing Admixtures
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 from gravel nests and honeycombing. It is compatible with all types of cement, sand and avoids efflorescence and bleed in concrete.
It improves workability thus improving compaction.
Reduces water cement ratio thereby increasing strength.
Increases resistance of mortars to attack by deicing salts and freeze and thaw cycles.
The concrete produced with Perma Plast AEA is homogeneous and free from bleeding.
Air entrainment of microscopic bubbles assists in producing cohesive concrete free from bleed which reduces segregation.
FIELDS OF APPLICATION
Perma Plast AEA is specially suitable for preparation of concrete and plaster and masonry mortars to be used in marine atmospheres and in marine construction. It can be effectively used as an admixture for concrete prepared at site, ready mix concrete and light aggregate concrete. Perma Plast AEA is particularly suited for pre-cast industry. Addition of Perma Plast AEA avoids honeycombing.
INSTRUCTION FOR USE
Perma Plast AEA should be used or added during the mixing operation. it is necessary to carry out a preliminary site trial to determine the amount of air entrained in fresh concrete or mortars. The dosage of Perma Plast AEA depends upon the flow and air entrainment required. Preliminary trials should be conducted at site to determine the optimum dosages. After addition of the Perma Plast AEA concrete should be thoroughly mixed so as to achieve a uniform consistency and homogeneity.
Resistance to acids:Good.
