Product Description:


NZY-FN1, a high performance water reducer (high concentration type)  is produced by the processing and purification of naphthalene high performance water reducer, the β - naphthalene sulfonic acid salt formaldehyde condensates content is high, sodium sulfate content is low ( ≤ 5%). It conforms to the requirements of chemical admixture specifications for concrete: ASTM C494, Type F; ASTM C1017


1、 NZY-FN1 is suitable to make high flowing concrete, commercial concrete, pumping concrete, prestressed and reinforced concrete.

2、 NZY-FN1 can be used to make C10-C60 concrete with slump loss between 50mm and 70mm, or C60 concrete with slump between 180mm and 220mm

3、 Mixed with the recommended dosage of this product in concrete, under the condition of same cement content and slump value, it can reduce the mixing water consumption from 18% to 30%, and enhance the early strength and strength obviously.

4、 With the same conditions of strength and slump of the concrete, it can save the using amount of cement from 15% to 20%.

5、 NZY-FN1 can be used as raw material to compound accelerator, retarder, anti-freezing agent and pumping aid to satisfy requirements from different construction projects, techniques, materials and environmental temperatures.

6、 NZY-FN1 is compatible with Portland Cement, Portland Slag cement, Fly-ash Cement, Portland Pozzolanic Cement.etc
