Product Description: To address the issue of airport runway foundation subsidence, high-performance airport runway grouting material achieves rapid reinforcement through pressure grouting technology. This material has an initial fluidity greater than 320mm, allowing it to fully penetrate into foundation voids; with a 2-hour vertical expansion rate of 0.1%-0.3%, it effectively lifts the subsided pavement. In the treatment of airport runway foundation subsidence, the grouting material achieves a 3-day compressive strength of 40MPa and a bond strength with the base layer of 2.5MPa, successfully restoring runway smoothness.In the treatment of airfield pavement subsidence, the grouting material demonstrates excellent fluidity retention. The 30-minute fluidity retention value remains as high as 280mm, meeting the demands of large-scale grouting operations. Through optimized particle size design (maximum particle size ≤0.8mm), the material can be injected into cracks as small as 0.2mm, forming a uniform reinforcement system. Testing shows that after grouting, the deflection value of the airfield pavement is reduced by more than 60%, effectively enhancing the pavement's load-bearing capacity.To address uneven settlement of apron pavement, the grouting material employs a composite expansion component. During the curing phase, it generates continuous expansion pressure, precisely lifting the settled areas. Its 7-day flexural strength is 6.5MPa, with an elastic modulus of 18GPa, ensuring coordinated deformation with the existing pavement. After grouting reinforcement, the apron pavement smoothness deviation is ≤2mm/3m, meeting the operational requirements of precision equipment.This grouting material achieves a balance between high fluidity and early strength through ultra-fine active mineral admixture technology. Even at a water-to-material ratio of 0.18, it maintains good pumpability, with a single-hole grouting influence radius of up to 1.2m. The material achieves a 28-day impermeability grade of P14 and freeze-thaw resistance exceeding F300, ensuring long-term stability of the reinforcement effect.The construction utilizes an intelligent grouting system that monitors grouting pressure and flow changes in real time. Grouting pressure is controlled between 0.5-1.0MPa, and elevation restoration is precisely managed through a lifting monitoring system. Traffic can be reopened just 2 hours after grouting, as the grouted body forms a complete load-bearing system with the base layer. After 10,000 fatigue load tests, no interlayer detachment has been observed. more>

The flexural strength is significantly higher than that of ordinary mortar, and the bonding strength with old concrete usually exceeds 1.5MPa, even reaching above 2.0MPa, effectively preventing debonding and spalling of the repair layer.Tensile Strength: Markedly improved, addressing the brittleness of cement-based materials.Durability and Protective Performance:Chloride Ion Penetration Resistance: The electric flux value or chloride ion diffusion coefficient is far lower than that of ordinary mortar, effectively blocking chloride ion intrusion, protecting internal reinforcement, and delaying steel corrosion.Resistance to Acid and Salt Erosion: After dry-wet cycle tests, the strength loss rate is much lower than the standard requirements, making it suitable for environments subject to seawater corrosion.Freeze-Thaw Resistance: After 300 freeze-thaw cycles, the relative dynamic elastic modulus can remain above 80%, with minimal mass loss, making it suitable for docks in northern freezing regions.Abrasion Resistance: The wear loss is significantly lower than that of ordinary cement mortar, enabling it to withstand long-term冲刷 wear from water flow carrying sediment.Water Permeability Resistance: The impermeability grade can reach above P10, demonstrating good compactness.Typical Damage Repair Applications in DocksPropylene emulsion mortar is suitable for repairing various damages in dock structures caused by冲刷, wear, corrosion, freeze-thaw, and other factors:Repair of Panel Concrete Spalling and Steel Corrosion: Remove loose concrete, perform derusting and rust prevention treatment on the reinforcement, and then use propylene emulsion mortar for layered pressing repair. Its high bonding strength ensures firm integration of new and old materials, while its impermeability and corrosion resistance provide long-term protection for the repaired area and reinforcement.Repair of冲磨 Damage in Water Level Fluctuation Zone and Splash Zone: This area is most severely affected by waves, ice flow, floating object impacts, and sediment冲刷. The excellent impact wear resistance and freeze-thaw resistance of propylene emulsion mortar make it an ideal material for surface repair of components such as beams, slabs, and columns in this area, effectively extending the service life of the structure.Protection and Repair of Pile Foundations: For damaged anti-corrosion coatings on steel pipe piles or surface damage on concrete piles, applying propylene emulsion mortar can serve as a protective reinforcement layer, resisting seawater corrosion and minor collisions from vessel berthing and departure.Crack Grouting and Defect Repair: For stable cracks in concrete structures, low-viscosity propylene emulsion mortar can be used for pressure crack filling; for surface defects such as honeycombs and pockmarks, propylene emulsion mortar can be used for leveling repair.Key Controls in Construction ProcessSubstrate Treatment: Must be thoroughly roughened, cleaned, fully moistened but without free water, which is a prerequisite for ensuring bonding effectiveness.Material Preparation: Strictly mix according to the design ratio (typically the propylene emulsion content is about 15%~20% of the cement weight), ensure uniform mixing, and control workability.Construction and Curing: During application, compact and smooth the mortar. After construction, it is advisable to cover with plastic film for moisture retention first, followed by water sprinkling curing for no less than 14 days to ensure good formation of the polymer film.Through its comprehensive performance, propylene emulsion mortar provides a reliable technical solution for the durability repair and protection of dock hydraulic concrete structures. more>
