The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate and dicalcium silicate. Suitable gypsum and ***0% limestone shall be blended with clinker during manufacture of rapid-hardening sulphoaluminate cement. The product is hydraulicity binding material. It has high early strength. Main technical indexes Specific surface area(m2/kg): ≥**0 Setting time(min): initial setting time: ≥*5 Final setting time: ≤**0 (Remark: the setting time can be adjusted according to the customers demand.) Strength data in different ages: 1d, Compressive strength (Mpa):*3.0MPa 3d, Compressive strength (Mpa):*2.5MPa *8d, Compressive strength (Mpa):*5.0MPa. 1d, Bending strength (Mpa):6.0MPa 3d, Bending strength (Mpa):6.5MPa *8d, Bending strength (Mpa):7.0MPa Properties 1) High early strength and high strength properties Its compressive strength can reach ****0Mpa within 1 day, ****0Mpa after 3 days, and it also can grows continually with the increasing of curing age 2) High froze-resistance property: If used at the temperature as low as ***0, which early strength is **6 times than that of OPC; if used in ***0 with little admixture, its strength in **7d can reach ****0% of designed strength, with very little strength loss after **0 times of froze-thaw circle. 3) High impermeability: because of its dense structure, the impermeability of the concrete is **3 times than that of OPC in same grade. 4) Anti-carbonation property: it has good anti-carbonation property, and low dry-shrinkage. 5) Corrosion-resistance Applications ***** in winter. 2.Urgent repairs and rapid construction. 3.Spraying anchor and supporting engineering. 4.Water conservancy facilities and offshore projects. 5.Bridge and road construction. ***** products and prefabricated components. 7.
