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.
