HSCA (soundless cracking agent), also widely known as expansive mortar, stone cracking powder, or non-explosive demolition agent, performs best within a specific temperature range.
The recommended ambient temperature for using HSCA is typically between 5°C and 40°C. Within this range, the hydration reaction can generate stable expansion pressure for effective rock splitting.
If the temperature is too low, the chemical reaction may slow down and delay the cracking process. In very hot environments, the reaction may occur faster, which can shorten the working time during mixing and filling.
For projects in extreme climates, different formulations of soundless cracking agent are usually selected to match winter or summer conditions and ensure reliable cracking performance.
