Alkali-free powder accelerator for tunnel and mining shotcrete applications. Alkali-free formula reduces strength loss and corrosion risk. Learn technical characteristics, applications, and usage guidelines.
What is Alkali-free Powder AcceleratorAlkali-free powder accelerator is a specialized admixture designed for shotcrete applications, supplied in powder form for convenient transportation, storage, and dosing. Unlike traditional liquid or alkali-containing accelerators, this type of product does not contain alkaline components such as sodium hydroxide or sodium carbonate. This formulation allows for rapid setting while minimizing negative impacts on the long-term strength and durability of concrete. The development of alkali-free formulations represents a significant advancement in accelerator technology. While alkali-containing accelerators offer fast setting times, they often lead to late-a
