Naphthalene-Based Superplasticizer

Naphthalene Superplasticizer
1.Appearance:Light brown powder
2.Contact tracy
3.PH value 7--9
Advantages
· Improve durability and manufacture high-strength concrete due to the decrease of unit quantity.
· The quantity of cement used is lowered and the bleeding phenomenon of material separation is decreased.
· Excellent workability and water tightness are secured.
Applications
· Briges, very high buildings and structures that require durability and high strenght.
· SOC structures including LNG bases, highways, railway, subway construction and tunnels.
· Concrete with high contents of fly ash, blast furnace slag or silica fume.
· Manufacture of prefabricated, precast and prestressed concrete.
· Manufacture of self-leveling con crete.
