Denka SC-1®
Ultra-rapid-set for tunnels, shotcrete & emergency repair
Ultra-fast setting accelerator based on amorphous calcium aluminate (ACA) and anhydrite. For the shortest setting times and high early strengths.

Accelerating additives
Newchem accelerating additives enable the shortest setting times and rapid strength development – ideal for shotcrete, precast plants and demanding concrete repairs.

Technology that wins time
Our accelerator technology is based on highly reactive calcium aluminates and special additives that precisely steer hydration and significantly reduce setting time – without compromising workability or durability.
Setting in minutes – ideal for shotcrete and emergency repairs.
Quickly reaching high early strengths for rapid load-bearing.
Reliable performance even at low temperatures and in difficult conditions.
Compatible with all common cements and concrete admixtures. Chloride-free.
