SUNBO SM superplasticizer is a high water-soluble anionic polymer dielectric, its cement has a very strong adsorption and dispersion, is the comprehensive index of existing concrete water reducer in one of the better water-reducing agent. SM's main features are: white, water-reducing rate, non-bleed type, chloride ion content is low no corrosion of steel, cement and all kinds of good adaptability. After using the SM, the early strength of concrete and significantly increased impermeability, construction, water retention and better, steam curing adapt well. SM not only for concrete, precast concrete, concrete pipe, also particularly suitable for exposed concrete, decorative concrete, self-leveling concrete. In addition, SM can also be used in the gypsum as a superplasticizer in order to improve the strength of gypsum products. This product meets the national standard GB8076-1997 superplasticizer indicators.
