Naphthalene superplasticizer FDN has a water-reducing rate, neither retarded nor entraining, adaptability, etc., can greatly improve the workability of concrete mix to reduce water consumption, and can significantly improve concrete strength. As a variety of composite concrete admixtures major masterbatch, additives with other varieties were complex, but also produce a variety of engineering requirements for concrete admixture products. The product helps to improve the quality of construction, improve construction efficiency, reduce construction costs and accelerate the progress of works. ■ Scope 1. Applicable to cast, precast, prestressed reinforced concrete and fly ash concrete, etc; 2. For the preparation of early strength, high strength, high permeability, high durability and self-compacting concrete; 3. For the Nature Conservancy and steam curing of concrete projects and products; 4. formulated C30-C60 concrete, appropriate increase in dosage and adding mineral admixtures in concrete can be formulated C70-C80 high strength concrete. ■ Key Features 1. This product is non-toxic, non-flammable, stable shape, no corrosion of steel effect; 2. Do not bleed air, concrete appearance of smooth and beautiful; 3. 15-30% water reduction, improve Mixture liquidity, Concrete slump can reach 18-25cm; 4. to cement a strong dispersion, and significantly improve the workability of mixture to make concrete mixture is easy to pour, easy to vibration; 5. The concrete 1-7 days strength increased by 60-100%, high enriched products, 28 days strength increased by 20-40%, low-enriched products, 28 days strength increased 10-40%; 6. saving cement, while maintaining the same strength can be reduced 7-25% 7. Increase the density of concrete, reduce shrinkage and creep, improve concrete durability and prolong the service life of concrete; the amount of cement. ■ High concentrated product, recommended dosage is generally 0.4-1.0% powder, liquid, typically 1.0-2.5%; low-enriched products, recommended dosage is generally 0.5-1.2% powder, liquid, typically 1.2 to 3.0%. ■ Use 1. According to the project requirements, test after adjusting dosage; 2. General simultaneously with the mixing water added to the mixer. If the lag before adding or concrete pouring and stirring a little added plasticizing best. ■ Packaging and storage powder 25kg / bag or 40kg / bag, should damp packaging to prevent breakage; liquid 250kg / drum or in bulk, not the long-term exposure.
