Melamine Sulphonate Formaldehyde Condensate Concrete Admixture
MelamineSulphonate
SM type melamine
In addition, our product succeeds to wide application of well cementingengineering in DaqingOilfield as efficient dispersing agent. Also, it helps produce groutingmaterial based on casting equipment, self-leveling floor material, structuralwaterproof material with UEA or other material. When used in solution, ourproduct can benefit winter construction due to no precipitation at lowtemperature. It conforms to the requirements of chemical admixturespecifications for concrete: ASTM C 494, Type F.
Our melamine sulphonateformaldehyde condensate concrete admixture is no-toxic, no-corrosion andnon-combustible, featuring no-air-entraining, low alkali, effective control ofbleeding and strengthening of concrete, and especially reduced shrinkage ofconcrete, etc. Furthermore, it provides the advantages of high water reducingrate over 20%, no retarding, significant enhancement, low content of sodiumsulfate, low chloride content, strong adaptability to calcium
Besides, it could improve the viscosity of gypsum slurry, enhancing thebrightness, durability and abrasive resistance of the surface of gypsumproducts. Our product can also improve hardness and smoothness of floor surfacewithout any crack, and has key effect on color durability. Due to strong earlystrengthening, it helps increase concrete strength by 40~100%, 30%~70%, 30%~60%on day 1, 7 and 28 respectively.
