It is an ultra-early-strength concrete structural repair material formulated with cement as the base binder, high-strength material (quartz sand) as the main aggregate, supplemented by polymer powder, water-reducing agent, early-strength agent, expansion agent, anti-segregation agent, and other substances. It is suitable for repairing honeycombs, pitting, sanding, peeling, exposed aggregate, and fine cracks in cement concrete pavements on highways, toll stations, service areas, gas stations, airports, etc. The repair thickness can be as thin as 3mm, allowing traffic to resume 2 to 3 hours after construction. It is the preferred choice for traffic-preserving repairs.I. Application Scope

1. Surface micro-cracks, sanding, peeling, etc., caused by various reasons during concrete pavement construction.

2. Honeycombs and pitting on the pavement caused by improper construction operations or deicing salt erosion.

3. Exposure of coarse aggregate on concrete pavement due to traffic wear or damage caused by freeze-thaw cycles and fires.

4. Thin-layer repairs for low elevation concrete pavements that need leveling due to various reasons.

5. Similar defects in other concrete components.
