Sodium Polynaphthalene Sulfonate(PNS) is a sodium salt of the product obtained by the condensation polymerization of naphthalene sulfonic acid and formaldehyde. It is non-air entraining superplasticizer. It has good dispersing performance on the cement particles.

Compared with traditional plasticizer, it has higher water reducing rate, good performance for high flowing concrete, case-in-place concrete which require for early and high strength, precast concrete and parts etc. It also has good adaptability to common cement, widely use in roads, bridges, dams, power engineering, civil construction and others.

● High water reducing rate. By the recommended dosage, the water reducing rate can reach 16% -28%, with obvious performance of early strength.

● Improve the workability of concrete and enhance concrete property, such as fracture resistance, compressive resistance and long term strength etc.

● Save cost. In the case of maintaining the same workability and strength, cement consumption will be reduced, and can improve concrete fluidity, enhance the bonding between concrete and steel bar.

● Wide adaptability, cost-effective. It has good adaptability to various cement, such as silicate cement, ordinary Portland cement, slag cement, volcanic ash cement, etc.

● Be mother material to formulate other functional admixtures, like type of early strength, set retarding, pumping, and anti-freezing etc.

Recommended dosage is 0.5 – 1.5% by weight of cement. Therefore, in many cases it is advisable to carry out trial mixes.

For powder: Powder packed in 25kg bag/650kg/700kg jumbo bag.
