Product Description
Pre-stressed duct grouting material is a grouting material specifically designed for pre-stressed concrete structures. This product is scientifically formulated using a variety of high-quality raw materials, including premium cement, carefully selected aggregates, high-efficiency water-reducing agents, and micro-expansive components. It boasts excellent fluidity, bonding strength, and impermeability. After application, it effectively fills the pre-stressed conduits, ensuring a tight bond between the prestressing tendons and the concrete, thereby enhancing the structural load-carrying capacity and durability. It is easy to handle and suitable for grouting operations on various pre-stressed concrete components. With its stable performance, this product represents an ideal choice of grouting material for applications in bridges, construction, and other related fields.

7. Precautions for Use
Construction environment temperature: -5°C to 35°C. The water-to-cement ratio is an important performance indicator for this product. Please add water according to the manufacturer’s specified water-to-cement ratio, and use mechanical mixing equipment to ensure thorough and uniform blending before construction! If the water-to-cement ratio is improperly adjusted, it may affect the product’s performance. This product is a finished item—do not add any other substances arbitrarily, as this could damage its functionality and compromise the quality system! If this product has expired, it should be properly disposed of and no longer used. Any leftover material after mixing that has not been fully used must never be mixed with fresh material for further use! When carrying out outdoor construction in rainy weather, a rain shelter must be set up. The mixed material must be used within 30 minutes; once the initial setting time has passed, the slurry will begin to set and lose its effectiveness! Once the package is opened, the contents must be used up in one go to prevent moisture absorption and clumping.
