Sodium Naphthalene Sulfonate Formaldehyde Sulfonated Naphthalene Formaldehyde For Concrete Admixture Astm C494
Concrete Admixture Dispersant Sodium Naphthalene Sulfonate Powder Product Description:
Naphthalene series water reducing agent is a non - induced water - reducing agent.The chemical name naphthalene sulfonate formaldehyde condensate, which has a strong dispersive effect on cement particles.For preparation flow state of concrete, early strength, high strength requirement of cast-in-situ concrete and pre-cast component, have very good use effect, can improve and improve concrete performance, widely used in roads, Bridges, tunnels, DAMS, ports, electricity, water conservancy and civil engineering, pipe and natural curing to the system components, etc.

Usage:
1. Produces the high slump flowing concrete with no loss in strength.Produces low water/cement ratio concrete with high strengths.
3. Ideal for using in high strength concrete, flowing concrete, early strength concrete, precast steam curing concrete, prestressed concrete etc. where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
3. Be used as basic material to produce others compound admixtures, (such as accelerating and water-reducing admixture, retarding and water-reducing admixture, pumping antifreeze and pumping water-reducing admixture, etc.)
Advantages:
Substantial improvement in work-ability without increased water or the risk of segregation. Normal set without retardation, even when overdosed. Improved density and surface finish.
High water reducing rate. High strengths after 8 hours.
Compatible with Portland cement, Normal Portland cement, Portland Slag Cement, Flyash Cement, Portland Pozzolanic Cement, etc.
Improve workability (slump) of concrete when added into mixing truck.
Application Method and Notice:
1. Blend dosage range is 0.3-1.5%, and application blend dosage is 0.5-1.2%. Appropriate blend dosage can be selected according to project object and the materials used during application.
2. FDN powder is recommended to be applied in solution. It can be used in dry form, but make sure mix it thoroughly with concrete.
3. If this product is applied with adoption of stagnant water blending method or post-blend approach, water reduction and dispersion will be better.
4. This product can be formulated with concrete additives of other varieties. It can be “double blended” with blending materials such as fly ash, ground slag, etc. But the blend dosage shall be calculated based on the total of cementing materials.
5. When this product is used for the first time or cement variety is changed, concrete trial preparation shall be conducted according to the adopted materials and construction requirements in the field. Construction mixing rate shall be adjusted based on testing result to serve.
