Product Description
ZK-SO3 Alkali-Free Liquid Setting Accelerator is a type of setting accelerator with a sodium oxide equivalent content of no more than 1.0%. Its outstanding features include reducing alkali-aggregate reaction without compromising the strength and durability of concrete.
Uses
ZK-S03 has been developed for use in:
◆ Tunnel linings
Mine roadways
Shotcrete for subway support
Repair concrete for bridges,dams,and structural buildings
Advantages
◆ Alkali-Free and Chloride-Free: Sodium oxide equivalent content ≤1.0%, Chloride ion content <0.1%. Noncorrosive ,effectively reducing alkali-aggregate reaction and steel reinforcement corrosion.
Eco-friendly and Safe:Odorless and non-volatile to harmful gases.
Advanced Technology: Produced at room temperature, energy-saving ,environmentally friendly,and highly stable.
◆ Low Rebound Rate: Significantly reduces concrete rebound and minimizes material waste.
Excellent Durability:No loss in later-age strength,high impermeability, and significantly enhanced resistance to corrosion and chemical attack
Precautions
◆ The recommended dosage is 6%-9% by weight of binder. The exact dosage should be verified through testing.
It is recommended to use non-retarding water reducers for fresh concrete.
Fresh concrete should possess good water retention and workability.
Curing should commence within 4 hours after spraying and last for at least 14 days to prevent shrinkage cracking.
