1. Commercial Ready-mixed Concrete (Core Application): The most widely used scenario. H1 is the standard admixture for commercial concrete batching plants, which can significantly improve concrete workability, extend slump retention time, adapt to long-distance transportation and various on-site construction requirements, ensure stable concrete quality from plant to construction site, and improve construction efficiency.

2. High & Ultra-high Strength Concrete: Suitable for C60 and above high strength, ultra-high strength concrete projects. Through its ultra-high water reduction capacity, it greatly reduces the water-cement ratio while maintaining good construction performance, significantly improves concrete compactness and mechanical strength, and meets the requirements of key projects such as high-rise buildings, long-span bridges and nuclear power facilities.

3. Pumping Concrete: Endows concrete with excellent fluidity and pumpability, reduces pumping resistance, lowers the risk of pipe blockage, greatly improves construction efficiency of high-rise and long-distance pumping projects, and is suitable for various pumping construction scenarios of urban buildings and infrastructure.

4. Self-compacting Concrete: Enables concrete to achieve excellent self-leveling and self-compacting performance, which can be densely formed without vibration. It is suitable for construction of components with dense reinforcement, complex structure and thin wall, solves the construction difficulty of special-shaped structures, and improves construction quality and efficiency.

5. Precast Concrete Elements: Applied in precast concrete component factories. It can achieve high early strength effect, accelerate mold turnover, improve production efficiency, and ensure good surface finish and stable mechanical properties of precast products, suitable for various prefabricated building components and industrial precast parts.

6. High Early Strength Low W/C Ratio Concrete: Suitable for projects requiring fast strength development and low water-cement ratio, such as winter construction and rush-schedule projects. It shortens concrete curing period, speeds up construction progress, and ensures stable long-term strength growth and durability of concrete.

A1: The recommended dosage is 0.2-1.0% of the total weight of cementitious materials. The optimum dosage must be confirmed through concrete trial mixing tests according to specific raw material types, concrete strength grade and construction performance requirements. Appropriately extending mixing time is suggested to achieve uniform dispersion and the best performance.

A2: No. H1 polycarboxylate superplasticizer cannot be mixed or used together with naphthalene series superplasticizers. Incompatibility between different types of admixtures will cause problems such as sharp slump loss, workability deterioration and even abnormal concrete setting. When switching admixture types, the mixing equipment and dosing system must be thoroughly cleaned.

A3: H1 should be stored in tightly sealed original containers at an ambient temperature of 0-40℃. Measures must be taken to prevent freezing and long-term direct sunlight exposure. Under proper storage conditions, the minimum shelf life is 12 months. If the product exceeds the shelf life, it must be tested and confirmed qualified before use.

A4: Both application methods are available. H1 can be directly added to the mixer together with mixing water according to the calculated dosage. It can also be diluted with clean water to the required concentration to adapt to on-site automatic dosing systems. When diluting, the dosage must be accurately converted according to the actual solid content to avoid performance deviation.

A5: No. H1 polycarboxylate superplasticizer has a chloride ion content of ≤0.1% and contains no corrosive components to steel reinforcement. It will not induce steel bar corrosion in concrete, and can effectively ensure the long-term durability and structural safety of reinforced concrete buildings, suitable for various reinforced concrete structures.

A6: H1 has good adaptability to most common cementitious materials, including ordinary Portland cement, composite cement, fly ash, ground granulated blast furnace slag powder and other mineral admixtures. For special cement types or special mineral admixtures, it is recommended to conduct a compatibility test first to confirm the optimum dosage and use effect.
