How Does HSCA (Soundless Cracking Agent) Work?

HSCA (soundless cracking agent), also known as expansive mortar or non-explosive demolition agent, works by generating extremely high expansion pressure inside drilled holes.

After the powder is mixed with water and poured into pre-drilled holes in rock or concrete, a hydration reaction occurs. This reaction produces strong expansion pressure that can exceed 120 MPa.

The expansion pressure gradually builds inside the drilled holes and creates internal stress within the rock or concrete structure. As the pressure increases, controlled cracks begin to form and the material splits along the drilling line.

Because this process does not involve explosives, HSCA provides a safe, vibration-free, and environmentally friendly method for breaking hard rock and reinforced concrete in quarrying, mining, and demolition projects.
