Concrete Superplasticizer

NSF full name is Naphthalene Sulfonate formaldehyde condensate. Its high purity makes cement paticles with high dispersancy, low foaming, high range water reducing and obvious strengthening so that we can get advantages of accelerating project mould turnover and construction speed, and also saving cement, improving cement mobility and workability.

Performance 1. Main ingredient is β-naphthyl sulfonate formaldehyde condensate, sodium sulfate≤20.0%. 2. Powder or liquid. The powder appears to be brownish yellow, and the liquid appears to be tan. Both are nontoxic, odorless and incombustible. 3.

Blend dosage 0.31.5% for powder (as cement amount), recommended blend dosage 0.75% for powder (as cement amount). 4.

When added into concretes: (1)While keeping the cement consumption and slump unchanged, water reduction will reach more than 20%, and increase 1d compressive strength of concrete up to 60100%, 3d compressive strength up to 5090% and 28d compressive strength up to 3050%, to be further reinforced in later period.

(2)While keeping the water-cement ratio and water consumption unchanged, concrete slump can be increased by more than 120mm. (3)While keeping the slump and compressive strength basically unchanged, consumption of cement can be saved by over 18%.
