Detailed Product Description

Cement

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.

Main technical indexes

Specific surface area(m2/kg): ≥350

Setting time(min): initial setting time: ≥25

Final setting time: ≤180

 (Remark: the setting time can be adjusted according to the customers demand.)

Strength data in different ages:

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,which early strength is 5-6 times than that of OPC; if used in 0-20 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.
