Sodium Naphthalene Formaldehyde SNF-A is used as concrete additive
Naphthalene series superplasticizer is a non - entrained superplasticizer synthesized by chemical industry. Chemical name naphthalene sulfonate formaldehyde condensates, it has a strong dispersion of cement particles.
Main technical performance:
1. This product conforms to the national first-class standard of concrete admixture GB8076-2008.
2. The dosage is 0.5-1% of the cement dosage, and the water reduction rate is 18-28%; The strength of one day and three days can be increased by 60% to 90%, and the strength of 28 days can be increased by 25% to 60%, and the long-term strength is still improved.
3. Under the same water-cement ratio, the collapse of SNF-A (0.75%) is 5-8 times higher than that without SNF-A.
4. When the strength and collapse degree of concrete are basically the same, adding SNF-A can save 15%-20% of cement.
5. Improve the workability and mechanics of concrete components, structural performance, improve the compatibility, impermeability, durability, is the high quality admixture of C70/C80 high efficiency concrete.
6.SNF-A has a wide range of applications, especially suitable for the preparation of high efficiency and ultra-high strength concrete; Steam curing concrete, fluid concrete, impervious concrete, waterproof concrete, plasticized concrete, reinforced concrete and prestressed reinforced concrete.
Instructions for use:
1. The dosage of this product is generally 0.5%-1.0%, and the recommended dosage is 0.75%.
2. This product can be used as solution or dry blending method.
3. Mixing type concrete transporter, also can be added during construction.
Please note: when replacing the cement variety with this product for the first time, necessary concrete experiments should be done according to the specific conditions and requirements of the tools. In the construction process, pay attention to the actual performance of FDN-A mixing, summarize the practical experience effect to make adjustments, in order to obtain the best effect. Reasonable maintenance conditions and systems are also determined during steam maintenance.
