Description of cement water reducer
The main component of TR-NSF naphthalene water reducer is ß-naphthalenesulfonate formaldehyde condensate, which is anon-air-entraining water-reducing agent. Its form is powder and liquid. The agent has good adaptability to various cements, improves the operability of concrete, and is widely used in highways, railways, bridges, tunnels, power stations, dams, high-rise buildings and other projects.
Technical index of cement water reducer
Appearance: powder brown yellow powder. Solid content: ≥92%; PH value (5% aqueous solution): 7-9. Sodium sulfate content: powder 16%-19%. Fluidity of cement paste: ≥200mm. Under the same water-cement ratio, the concrete slump can be increased by more than 10cm. When keeping the slump unchanged, the water reduction rate can reach 12%-20%.
It has significant early strength and synergistic effects on concrete, and its strength is increased by 15%-40%. It can comprehensively improve and enhance the physical and mechanical properties of concrete, and can save 10%-20% of cement while maintaining the same strength. No corrosion to steel bars.
Instructions of cement water reducer
The powder is 0.5%-1.5%, and the recommended dosage is 1%. According to the grade of concrete, the dosage can be increased appropriately.
Packaging and storage of cement water reducer
Packed in double-layered woven bag with inner plastic film, 25kg or 40kg per bag; liquid: in iron drum, 250kg per drum.
Rainproof and moisture-proof, store in a ventilated and dry place. The validity period is three years, and it can still be used after passing the concrete test.
