Model NO.: FDN-A Usage: Construction Chemicals Name: Sodium Naphthalene Sulfonate Formaldehyde pH: 7-9 Trademark: YUANSHENG CHEMICAL Origin: Shandong, China Appearance: Powder Color: Brown Sodium Content: 5% Solid Content: >93% Specification: SGS HS Code: 3824401000 Sodium Naphthalene Formaldehyde Dispersant Sulfate(FDN-B)
Description:
The
Naphthalene Superplasticizer is a chemically synthesized non-air-entrained superplasticizer, with chemical name of naphthalene sulfonate formaldehyde condensate. It has strong dispersion effect on cement particles and good use effect of preparing super flowing concrete as well as cast-in-situ concrete and precast members with early strength and high strength requirements, can comprehensively improve various properties of the concrete, and is widely applied to highways, bridges, dams, harbors, tunnels, electric power, water conservancy as well as industrial and civil architecture, steam-cured and naturally-cured precast members and so on.
Product Performance:
1. Reduce 10 to 25 percent of cement content when the strength and the slump of the concrete are basically same.
2. When the water cement ratio is constant, it improves the initial slump of the concrete by more than 10cm, and the water-reducing ratio can reach 15-25%
3. Has remarkable early strength and strengthening effects on the concrete, and improve the strength by 20-60%.
4. Improve the workability of the concrete and comprehensively improve the physical and chemical properties of the concrete.
5. Adapt to various cements well, and is well compatible with other types of 0s.
6. Particularly applicable to the following concrete projects: flowing concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, naturally-cured precast member concrete, reinforcing steel bars and prestressed reinforced concrete, high-strength and ultra-high-strength concrete.
