Naphthalene Sulfonate Formaldehyde Condensate Water Reducing Admixture

A high-performance water reducer in the plasticizer category, the naphthalene-based variant is an anionic surfactant made from industrial naphthalene via chemical processes like sulfonation, condensation, and neutralization. Its key component, naphthalene sulfonate formaldehyde condensate, makes it one of the most prevalent concrete admixtures.

• High Water Reduction: Rate of 15%~25%, significantly lowering the water-cement ratio and enhancing strength.
• Strength Enhancement: Increases compressive strength by 20%~40%, with notable early-stage development.
• Improved Workability: Enhances concrete fluidity, facilitating pumping and placement.
• Retarding Effect: Extends initial setting time by 1~3 hours, beneficial for summer construction.
• Low Air Entrainment: Air content typically <3%, ensuring durability.

Construction Projects: Cast-in-place concrete, precast components.
Infrastructure: Roads, bridges, tunnels, water conservancy.
Special Concrete: High-strength (C50+), pumping, mass concrete.
Precast Elements: Pipe piles, sleepers, segments.
