Rapid-Hardening cement
Sulphoaluminate Cement
The product obtained by grinding cement clinker obtained by roasting suitable raw material, consisting essentially of anhydrous calcium sulphoaluminate、 dicalcium silicate and teraclcium aluminate ferrite. Suitable anhydrite、slag and fly ash shall be blended with clinker during manufacture of improved rapid-hardening sulphoaluminate cement. It has high early strength. The product is hydraulicity binding material. The code No. is I-SAC.
The product carries out the standard: Q/ZTS01-1999.
The strength depends on its compressive strength at 7 days. There are two grades: 32.5 and 42.5.
The product achieved a class one civic prize of excellent new product, a class two provincial prize of excellent new product. The product is high-tech product by Hebei science department.

 Main technical data
1. specific surface area(㎡/kg): ≥350㎡/kg.
2. Initial setting time(min): ≥25
Final setting time: ≤180
The setting time can be adjusted by the customer’s request.
3. The strength in different terms are not less than the following :
Grade Compressive strength (Mpa) Bending strength (Mpa)
1d. 3d 7d 1d 3d 7d
32.5 27.0 30.0 32.5 4.5 5.0 5.5
Properties
1. Setting time is a little longer than R-SAC(Rapid-hardening sulphoaluminate cement),quite suit for RMC.
2. It can extend the working time, improve the concrete workability, early strength, rapid hardening, freeze-resistance, impermeability and little expansion etc..
3. Improving the sulphoaluminate cement that easy occurring sands in surface for incorrect curing.
4. The price is low.
 Applications:
Construction in winter
Urgent repair construction
Bridge and road construction
Concrete production
Common civil building
Water conservancy facilities and offshore projects
