Powdered, Non-chloride, Accelerating Admixture

ACCELGUARD SET-SPEED is a powdered accelerating admixture intended for use with cementitious based materials. ACCELGUARD SET-SPEED does not contain calcium chloride or added chloride ions. ACCELGUARD SET-SPEED improves the properties of plastic and hardened concrete, with significant improvements in early strength gain and setting characteristics, improved workability and decreased bleeding and segregation. ACCELGUARD SET-SPEED works well at all temperatures but has shown most benefit in the 35°F to 50°F (2°C to 10°C).
