ChemSpeed 75

Quick Overview

Areas repaired with ChemSpeed 75 can be returned to rubber wheeled traffic in only 2 hours (depending on temperature). ChemSpeed 75 meets ASTM C928 for rapid repairs of concrete and can be extended with pea gravel up to 60% for deep placements.

Uses

• Structural filling holes subject to heavy traffic including concrete decks, bridges and roadways.
• Full-depth patching of horizontal concrete.
• Fast setting repairs to high load concrete such as loading docks and industrial floors.
• Repairs adjacent to construction and expansion joints.

Advantages

• Initial set in 13-19 minutes at 72°F (22°C).
• Repairs from 0.50 inch (1.3 cm) to full depth.
• Nonshrink with exceptional bond strength.
• High early strength gaining 3000 psi (21 MPa) in 2 hours at 72°F (22°C)
• May be placed at temperatures down to 20°F (-6.7°C) if ACI 306 cold weather concreting standards are followed.
• Accepts rubber wheeled traffic over road surfaces or industrial facilities in one hour.
• Resists freeze-thaw cycles and deicing chemicals.
• May be extended for economical placement at depths greater than 1.5 inches (4 cm)
