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:

         Rapid-hardening cement 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.
