sulphoaluminate cement

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; ifused in 10-20℃ 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 the 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 than1 corrosion-resistance coefficient
