How to use the silent expansion agent correctly?

Silent expansion agent is a powdered high-efficiency and safe crushing material for the safe removal of concrete structures and mining of cut marble and granite. The HSCA is adjusted into a slurry and poured into a rock or concrete borehole with water. After 3 to 8 hours, the crushing or cutting operation can be carried out without vibration, no dry sound, no flying stone, and no harmful gas. This product has been widely used for many years. What should we pay attention to during the use?
