Urban Demolition Guide: Using Static Cracking Agent for Reinforced Concrete

In modern urban construction, demolishing reinforced concrete foundations or beams is a headache. Noise restrictions, dust control, and safety regulations often make it impossible to use heavy hydraulic breakers or explosives.

This is where Topking Static Cracking Agent (also known as Non-explosive Demolition Agent) becomes the ultimate solution. It breaks concrete silently using expansive pressure (up to 120 MPa), without vibration or flyrock.

Why choose Static Cracking Agent for Concrete?

Compared to traditional jackhammers, chemical demolition offers distinct advantages for city projects:

• Zero Noise: Perfect for residential areas, hospitals, and schools.

• Zero Vibration: Does not damage surrounding structures or pipelines.

• Easy Cleanup: Concrete breaks into manageable blocks, protecting the rebar for recycling.

Step-by-Step Guide: Demolishing Reinforced Concrete

Step 1: Drilling Pattern Design

Concrete is tougher than rock because of the steel rebars. To ensure efficiency, you need high-performance drilling equipment.

• Recommended Equipment: Use Topking                            Pneumatic Rock Drills (Jackhammers)                        paired with                            Q7 Tapered Bits            .            This combination cuts through concrete and rebar quickly.

• Hole Diameter: 38mm - 40mm.

• Hole Spacing: 20cm - 30cm (Closer than rock mining).

• Hole Depth: 90% - 100% of the concrete depth.

Step 2: Mixing and Filling

Mix the Static Cracking Agent powder with clean water (Ratio 1.5 liters water per 5kg bag). Stir until it creates a smooth slurry. Pour it into the holes within 10 minutes.

Pro Tip: For reinforced concrete, cracks usually appear within 12-24 hours. The concrete will crack between the rebars, separating the cement from the steel.

Step 3: Removal

Once the cracks are wide enough, use a small excavator or manual labor to remove the concrete chunks. You will find the steel bars are clean and easy to cut.

⚠️ Safety Note for Urban Projects

Always wear safety goggles and gloves. Even though it is "static," do not look directly into the holes after filling.            Check our full Expansive Mortar Product Line to choose the right model based on your city's current temperature.
