Dr. Plast 3132 (Retarder)

Product Overview

Retarders are concrete admixtures used to delay the setting time of concrete, preventing premature stiffening during placement and finishing. They are especially suitable for hot weather conditions and long pours, ensuring better workability and uniform concrete quality.

Key Features

• Extended Workability: Delays setting time for extended placing and finishing periods
• Hot Weather Solution: Counteracts the effects of high temperatures on concrete
• Long-Distance Transportation: Maintains workability during extended transit times
• Uniform Quality: Prevents cold joints in large continuous pours
• Better Finish: Allows more time for proper finishing and surface treatment
• Reduced Cracking: Controls heat of hydration in mass concrete

Applications

• Hot weather concreting
• Long-distance concrete transportation
• Large continuous concrete pours
• Mass concrete structures (dams, foundations)
• Decorative concrete requiring extended finishing time
• Complex architectural concrete forms
• Pumping of concrete over long distances

Technical Benefits

• Extends setting time by 1-4 hours depending on dosage
• Maintains concrete workability in high temperatures
• Reduces water evaporation effects
• Prevents cold joints in continuous pours
• Controls heat of hydration
• Compatible with all cement types
• Does not adversely affect final strength

Dosage and Application

Typical dosage ranges from 0.1% to 0.5% by weight of cement, with higher dosages providing longer retardation. The retardation period varies with temperature, cement type, and other admixtures present. Add during mixing to ensure uniform distribution. Our technical team can provide specific dosage recommendations based on your ambient conditions and project requirements.
