Perma Plast PC – 502



ASTM C494 : Type A, B, D & E
IS : 9103 – 2007


Perma Plast PC – 502 is a superior quality Super Plasticiser cum very high range water reducer based on high molecular weight Poly Carboxylic Copolymers.


  • To produce free flowing and self compacting concrete.
  • To increase the compressive strengths of the concretes and mortars to highest possible limits.
  • To bring down the water cement ratios to bare minimum.
  • To achieve early high strengths.
  • To achieve prolonged workability.


  • Perma Plast PC – 502 is a light colored liquid hence does not change the colour of concrete.
  • Perma Plast PC – 502 is highly useful in pre-cast units.
  • Perma Plast PC – 502 is of special advantage in concreting RCC members with congested reinforcements.
  • Perma Plast PC – 502 is very easy to dose. The dosing quantity of the material can be added to the concrete or mortar mix at any stage of mixing.


Perma Plast PC – 502 should be added to the concrete / mortar / cement paste mix during the mixing cycle at the same time as the water is added. Avoid adding Perma Plast PC – 502 directly to the dry cement.


Perma Plast PC – 502 is a powerful plasticiser which disperses and deflocculates the cement particles within cement concrete / mortar or in paste. It is useful in increasing the workability of mix without addition of excess water or to allow reduction in free water content of the mix to achieve superior strength without in any way affecting the colour of the mix or the end product.


Field trials should be conducted to determine the optimum dosage of Perma Plast PC – 502 for each application. However dosage range is between 100 gms to 1000 gms per 50 kg bag of cement depending upon the end results desired.


Typical properties of Perma Plast PC – 502 are as follows.

Form : Brown Colored Liquid
Specific Gravity : 1.10 at 25° C
PH : 7 ± 0.5
Air Entrainment : Nil
Chloride Content : Nil
Nitrates : Nil



Perma Plast PC – 502 is available in 25 kg, 100 kg and 200 kg packs.


Perma Plast PC – 502 has a shelf life of 24 months if stored in manufacturer’s original packing in a cool and dry place away from moisture and heat.
