SNF Powder Sodium Naphthalene Sulfonate Formaldehyde , Sodium Naphthalene Formaldehyde

Main properties:
1. this product meets the concrete admixtures GB8076-97 national grade standards.
2. volume of cement dosage of 0.5-1%, water-reducing rate for 16-22%; early obvious intensity increase 60-95% day, three days, 28-day strength more than 25-40%, long-term strength has greatly improved.
3. under the same cover, mix 0.7%, the slump of more than 4-6 times blank, still retains plasticity.
4. save the cement in the protection of design strength cases, concrete experience migraine can be saved.
5. improved workability, the mechanics of concrete, structural performance, increased impermeability and durability, and good frost resistance.
6. FDN-C water reducer widely applicable, suitable for high-strength concrete, steel reinforcement and stress of reinforced concrete, impermeability of waterproof concrete steam curing concrete and nature conservation, high fluidity concrete, preparation of freeze-thaw resistance of concrete and so on.
