Sulfonated Melamine-Formaldehyde Resin Superplasticizer

Product Brief:                                                                                               
Concrete High-range Water-reducer SM (Sulfonated Melamine-formaldehyde Resin) is a polymer electrolyte, SM is the best one of existing concrete admixture in comprehensive properties.
It is able to prepare high-strength concrete and flowing concrete by adding SM into Ordinary Portland Cement. For high-strength concrete the compressive strength will reach or surpass 80MPa．This concrete is largely used in high-raise building and many important prestressed concrete structure of civil engineering. The flowing concrete is usually used for in-site casting and pump concreting，such as mass foundation and other structure with closs arranging reinforcement .
It has a excellent compatibility for Aluminous Cement. It metallurgical industry SM is often used as major admixture for refractory concrete, included castables and field mixes.
The product of SM is of a white or transparent colourless water solution. Owing to this it can be extensively used in inorganic decorative materials such as man-made marble，terrazzo，paints and various gypsum products.

Principle Technical properties:

1．For dosage within 0.5～1.0％ by weight of cement，the water reduction rate will be 20～25％
2. When dosage is appropriate , It is able to increase the compressive strength of concrete and mortar by 40～100％ at one day，by 30～60％ at 28 days . The later age strength also in crease (about 20％) .
3. It is able to prepare high strength concrete (60～80MPa，even higher) by using 45.5#～55.5# Ordinary Portland Cement .
4．Adding SM to refractory concrete，from Aluminous Cement，the strength after drying at 110℃ and after burning at high temperature will increases obviously(by 60～170％ for compressive).
5. Because of no air-entrainment SM can be used curing of concrete and their products.
6. The SM is usually applied for α-hemi hydrate gypsum and β-hemi hydrate gypsum，When dosage is 0.5～1.0％ by weight of gypsum，It is able to increase the strength of gypsum by high water-reducing rate.

Safety Usage:
