PolyЯRon PC300 is a mid range water reducing and retarding plasticiser based on polycarboxylic ether which was specially designed for improving the concrete flow ability and strength by improving the properties of fresh and hardened concrete. It increases the dispersion of cement particles by electrostatic repulsion and steric hindrance that enables the water content in the concrete to perform to maximum efficiency accounting to lesser water-cement ratio with improved workability.

Advantages

• Better dispersion of cement particles with small adsorbed area.
• Exhibits combined properties of high water reduction and prolonged workability retention.
• Maintains concrete flowability over a long time.
• Provides high early compressive and flexural strengths.
• Low water cement ratio yields to low permeability.
• Reduction in permeability, yielding to increased durability.

Application area

PolyЯRon PC300 is suitable for all kinds of high strength, high cement content and low water cement ratio concrete. Typical application includes

• Self compacting concrete.
• Hot weather concreting that demands prolonged workability retention.
• More suitable for congested reinforcement.
• To avoid cold joints.
• To obtain low heat of hydration.

Applicable standards

PolyЯRon PC300 complies with ASTM C-494 type B, D&G.

Dosage

The normal dosage is 0.5 to 1.8 litre per 100kg cement. The optimum dosage should be determined by conducting laboratory/site trials considering proposed mix design, ambient conditions and performance requirement such as workability, early rate of hardening and compressive strength.
