Product Introduction
Rapid-Setting Concrete is an ultra-early-strength concrete structure repair material formulated with cement as the basic binding agent, high-strength material (quartz sand) as the main aggregate, supplemented by polymer adhesive powder, high-efficiency water-reducing agent, early-strengthening agent, expanding agent, and anti-segregation and other substances. This product has the characteristics of good self-flow, fast hardening, early strength, high strength, no shrinkage, micro-expansion; non-toxic, harmless, non-aging, no pollution to water quality and the surrounding environment, good self-tightness, rust-blocking and so on.
Why Choose Our Rapid-Setting Products?
1. Industry-Leading Speed & Strength
Fast-Setting Concrete:
20 MPa in 1 Hour (ASTM C1604) – Reopen traffic 4x faster.
Subzero Application: Works at -10°C with no heated equipment.
Concrete Repair Mortar: 30-Minute Initial Set– Patch potholes before peak traffic.
Bond Strength ≥2.5 MPa(EN 1542) – Outlasts original concrete.
2. Unmatched Versatility
All-Weather Use: Resists rain/snow within 15 minutes of pouring.
Multi-Surface Adhesion: Bonds to concrete, asphalt, steel (tested per ASTM C882).
Custom Mixes: Choose flowable (slump 200mm) or non-sag grades.
Highway Potholes: 2-hour repair with 10+ year lifespan .
Bridge Deck Spalls: Restore load capacity overnight.
Airport Runways: FAA-spec rapid repairs .
Warehouse Floors: Fix forklift damage during night shifts.
Parking Garages: Permanent repair of scaling/cracking.
Arctic Oil Rigs: Cure at -20°C with anti-freeze additives.
Coastal Structures: Chloride-resistant (≤0.1% Cl⁻ penetration).
Q:Can I apply it over wet surfaces?
A: Yes! Our HydroShield Additive allows application on damp concrete.
Q:Does it match existing concrete color?
A: Custom tints available (RAL/ Pantone matching).
