Product Description
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 0-10% limestone shall be blended with clinker during manufacture of rapid-hardening sulphoaluminate cement. The product is hydraulicity binding material. It has high early strength. The code no is R-SAC and with four grades.
L Main Specification:
Specific surface area(sqm/kg): ≥ 350
Setting time(min): Initial setting time: ≥ 25
Final setting time: ≤ 180
(Remark: The setting time can be adjusted according to the customer's demand. )
Properties:
1) High early strength and high strength properties
Its compressive strength can reach 35-50Mpa within 1 day, 50-70Mpa 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 0-10 degree, which early strength is 5-6 times than that of OPC; If used in 0-20 degree with little admixture, its strength in 3-7d can reach 70-80% of designed strength, with very little strength loss after 300 times of froze-thaw circle.
3) High impermeability: Because of its dense structure, the impermeability of the concrete is 2-3 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: It has good corrosion-resistance quality, especially much better in seawater corrosion resistance than that of high anti-sulphate Portland cement, with more than 1 corrosion-resistance coefficient.
Applications:
1. Construction 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.
6. Cement products and prefabricated components.
