naphthalene super plasticizer

We can produce 12,000 metric tons of solid water reducing agent of the naphthalene family.

Naphthalene water reducing agent products are suitable for all grades of cement. The use of such products will offer 25% of water reducing rate, 20-40% of reinforcement result, and a saving of 20-50 metric tons of cement for one metric ton of water reducer. The products are extensively used in such works as highways, bridges, harbors, wharfs, water conservancy facilities, industrial projects and civil buildings.

a) Solid content≥92%,

b) Water reducing ratio≥20-30%,

c) PH amount ≥8,

d) Content of Sodium Sulfate  below 3%,

e) Fineness: 5%max.   

f) Sieving residue  below 15%,

g) Surface Tension below 60 seconds,

h) Concrete Reducing Water Rate≥22cm.
