Product Description
HSCA-2 Standard Grade Stone Soundless Cracking Agent
SCA-2 Stone Soundless Cracking Agent is a high-performance non-explosive expansive mortar formulated for standard-temperature applications where material temperatures range from 10°C to 25°C. This versatile grade is the most widely used formulation, suitable for spring, autumn, and moderate-climate projects year-round.
After mixing with clean water at approximately 28–30% by weight and pouring into pre-drilled boreholes, HSCA-2 undergoes a controlled hydration reaction that generates powerful radial expansion pressure of approximately 120–130 MPa. This static pressure exceeds the tensile strength of rock and concrete, creating controlled fractures without explosives, vibration, or fly rock.
Applications
- Dimension Stone Quarrying: Controlled splitting of granite, marble, limestone, and sandstone while preserving valuable stone blocks.
- Boulder and Rock Breaking: Breaking oversized boulders, natural rock formations, ledges, and excavation obstructions.
- Concrete Demolition: Removal of plain and reinforced concrete foundations, slabs, columns, piers, and machinery bases.
- Mining Operations: Secondary breaking of oversized rocks and controlled excavation in restricted blasting areas.
- Road and Trench Construction: Rock removal for road widening, pipeline trenches, drainage systems, and underground utilities.
- Bridge and Dam Projects: Controlled removal of concrete sections near sensitive or load-bearing structures.
- Pre-Splitting and Controlled Cutting: Creating planned fracture lines for predictable rock sizes and shapes.
- Environmentally Sensitive Projects: Rock and concrete removal where noise, vibration, dust, and flying debris must be minimized.
Features and Advantages
| Feature | Customer Benefit |
|---|---|
| Non-Explosive Technology | Breaks rock and concrete through static expansion rather than detonation |
| Soundless Operation | Suitable for noise-sensitive urban, residential, and industrial locations |
| Minimal Vibration | Reduces risk of vibration damage to nearby buildings, equipment, and underground services |
| No Fly Rock | Gradual crack development improves job-site safety and control |
| High Expansion Pressure | Approximately 120–130 MPa under suitable application conditions |
| Controlled Cracking | Hole position, spacing, and depth can be designed to guide fracture direction and size |
| Simple Application | Standard operation: drill, mix with water, and fill the prepared holes |
| Versatile Temperature Range | Reliable performance at material temperatures of 10°C–25°C for spring, autumn, and moderate climates |
| Reduced Heavy Equipment Use | Reduces dependence on hydraulic breakers, jackhammers, and large demolition machinery |
| Convenient Transportation | Dry powder packed in moisture-resistant inner bags and export cartons for palletized shipment |
| Private Label Service | Customized brand, carton printing, inner bags, and export pallet packaging available |

Safety and Storage Notice
Important: The powder and freshly mixed slurry are strongly alkaline. Operators must wear suitable gloves, eye protection, protective clothing, and respiratory protection during mixing and filling. Do not look directly into filled boreholes, do not cap the holes, and keep personnel away during the reaction period. Store unopened bags in a dry warehouse on pallets and protect from moisture. Product use must follow the supplier's technical data sheet, safety data sheet, and local regulations.
