HSCA Soundless Expansive Mortar Non Explosive Demolition Agent Static Cracking Powder for Rock Concrete

Non-Explosive Demolition Agent (HSCA) - Soundless Expansive Mortar

Key Features & Advantages

• Massive Expansion Force: Generates up to 120 MPa (1200 kg/cm²) of expansive pressure, sufficient to crack the hardest rock and reinforced concrete.
• Rapid Reaction Time: Maximum expansion force can be achieved within 1 hour. Reaction time is adjustable from 1 to 12 hours to suit project requirements.
• Soundless & Safe Operation: No vibration, no noise, no flying debris, no dust, and no toxic gas emissions. Safe for use in urban areas, residential zones, and sensitive environments.
• Controlled Precision Cracking: Millimeter-level precision for directional cracking. Break what you need, preserve what you want. Ideal for projects requiring structural integrity of surrounding areas.
• Wide Temperature Adaptability: Available in multiple models (Type I, II, III) covering temperatures from -5°C to 40°C. Low-temperature model maintains over 85% expansion rate at -5°C.
• Easy Application: Simple mixing with clean water, pour into drilled holes, and compact. Minimal operator training required.
• Long Shelf Life: 12-month shelf life when stored in dry, temperature-controlled conditions (16°C-32°C) with intact packaging.
• Eco-Friendly & Non-Hazardous: Non-flammable, non-explosive. Classified as ordinary goods for transport and storage. No harmful residues after use.

Applications

• Mining & Stone Quarrying: Precision cutting and extraction of granite, marble, limestone, jade, and other valuable dimensional stones. Increases stone yield rate by 2-3 times compared to blasting methods.
• Construction Demolition: Demolition of building foundations, bridge piers, dams, columns, beams, walls, and reinforced concrete structures, especially in urban areas, residential zones, and near public facilities.
• Infrastructure Projects: Tunnel and channel excavation, subway construction, shaft sinking, pile excavation, and trench cutting without vibration damage to surrounding underground utilities.
• Sensitive Environments: Demolition near schools, hospitals, heritage sites, and cultural relic protection areas. Safe for use in hazardous material storage areas where open flames are prohibited.
• Emergency Rescue: Rapid obstacle removal in post-earthquake, landslide, or other disaster rescue operations.
• Other Applications: Refractory lining removal in high-temperature kilns, pre-splitting assistance for controlled blasting, non-shrink grouting for machinery anchor bolts and base plates.

Expansion Pressure by Model & Temperature

Usage Instructions

1. Pre-Operation Check: Verify ambient temperature, powder temperature, water temperature, and material temperature are within the selected model range. Inspect packaging integrity.
2. Drilling Design: Determine at least one free face. Drill holes parallel to the free face. Keep holes in the same plane for cutting applications. Adjust hole diameter, spacing, and depth based on material type, strength, and desired fragmentation.
3. Mixing: Pour clean water into a mixing container first, then add powder gradually. Mix ratio: 0.24 kg water per 1 kg powder (1.2 kg water per 5 kg bag). Stir thoroughly to achieve a uniform slurry.
4. Pouring: Pour the slurry into drilled holes immediately after mixing. Compact with a tamping rod to eliminate air pockets. Complete filling before dark or when ambient temperature is below the design temperature.
5. Post-Pour Monitoring: Do not look directly into holes within 4 hours. Ensure waterproof covering to prevent rain ingress. Cracking typically occurs within 2-24 hours.
