Liquid Shotcrete Accelerator

Liquid Shotcrete Accelerator

Accelerator for Shotcrete Mortar

What is Liquid Shotcrete Accelerator?

Liquid Shotcrete Accelerator is an effective additive that rapidly reduces setting time and accelerates the hardening process of mortar and concrete. It is particularly useful in shotcrete applications and for repair work on concrete structures. Additionally, this product increases hydration temperature and prevents freezing of concrete.

Shotcrete is an essential method for strengthening structures, especially during tunnel construction, as it allows concrete placement without the need for formwork. Due to its adhesive properties, it is also used for repairs and strengthening of structures, making it feasible to work in cold weather.
