Sodium Naphthalene Sulfonate Formaldehyde
This product, named -naphthalene sulfonate formaldehyde condensate, is non-air entraining superplasticizer. It has good
dispersing performance to the cement particles. Compared with traditional plasticizer, it has higher water reducing rate, and good for preparing mass concrete, fresh concrete required for early strength and high strength, and precast concrete and parts. It also has good adaptability to commonly used cement, and widely used in roads, bridges, dams, power engineering, civil construction, steam and natural curing precast parts and other projects.
Advantage:
* Higher water reducing rate. By the recommended dosage, the water reducingrate can reach 15% -20%.
* Improve the workability of concrete, such as compression, long-term strength, flowability, etc., and enhance the reinforcement of steel and concrete.
* Reduce costs. In the case of maintaining the same workability and strength, cement amountcan be reduced.
* Wide adaptability, cost-effective. Good adaptability to all kinds of cement, such as Portland cement, slag cement, volcanic ash cement, etc.
* Be mother material to formulate other admixtures.(like early strength, set retarder, pumping agent, antifreezing agent).
