Product Introduction
High-Strength, Fast-Setting Repair Cement is a high-strength, rapid-hardening cement-based repair material suitable for localized repair of damaged concrete pavements, bridge decks, industrial flooring, parking lots, plant roads, and municipal roads.
The product is a composite material made of high-performance cementitious materials, selected fine aggregates, polymer-modified components, and functional additives. It features rapid early-strength development, strong bonding capacity, low shrinkage, and flexible application thickness. After application, it hardens quickly, making it suitable for emergency repair scenarios requiring short opening times.
Under standard curing and proper construction conditions, the product’s compressive strength can reach 60 MPa; a relatively high early strength is achieved in approximately 2 hours, meeting requirements for rapid repair, quick restoration of traffic, or subsequent construction. For thin-layer repairs, the minimum application thickness can be as low as approximately 3mm, making it suitable for surface defects, sanding, pitting, edge/corner damage, and small-area leveling repairs.
Core Selling Points
60 MPa High Strength
High structural strength after curing, suitable for repair areas subjected to repeated use by vehicles, pedestrian traffic, and industrial applications.
Dries in approximately 2 hours
Rapid early strength development shortens curing waiting time and improves repair efficiency for roads and floors.
Approx. 3mm Thin-Layer Repair
Suitable for thin-layer touch-ups, surface defect repair, edge and corner finishing, and localized fine repairs—reducing material waste.
Polymer-Modified, Strong Adhesion
Bonds tightly with the old concrete substrate, reducing the risk of hollow drums, delamination, and secondary damage.
Low Shrinkage, More Stable Repairs
Good volume stability after curing, suitable for repair projects requiring flatness and durability.
Ready to Use with Just Water—Easy Application
Simply mix with water on-site at the specified ratio for immediate application—no complex equipment required, making it ideal for small-area repairs and emergency repairs.

Construction Method
1. Substrate Preparation
Remove loose layers, floating dust, oil stains, and debris to ensure the substrate is solid and clean. For areas with insufficient strength or severe sanding, chisel away to a stable substrate.
2. Pre-wet the substrate
Before construction, the substrate may be moderately moistened—keep the surface damp but without standing water—to improve bonding between the material and the substrate.
3. Add water and mix
Add water according to the recommended water-to-cement ratio and mix with an electric mixer until a uniform, lump-free mortar is obtained. The mixing quantity per batch should be reasonably controlled based on the working time.
4. Troweling or Spreading
Apply the mixed material to the repair area by troweling, compacting, or spreading. Thin-layer repairs can start from approximately 3mm; deeper potholes require layered application.
5. Surface Curing
Leveling and finishing must be completed before the initial setting of the material. In high-temperature, high-wind, or dry environments, moisture-retaining curing is required to prevent rapid surface water loss.
Precautions
- The actual open time is affected by temperature, humidity, application thickness, amount of water added, and substrate conditions.
- Curing time may be extended in low-temperature environments, and working time may be shortened in high-temperature environments.
- Direct application is not recommended on substrates that are loose, oily, severely damp, or have standing water.
- It is recommended to conduct a small-scale test before large-area application to confirm bonding performance, color, and surface condition.
- If used in heavy-traffic areas, the construction thickness and curing time shall be determined according to engineering requirements.
