1. Rapid hardening CSA cement:
Rapid-hardening hydraulic cement is not only a more durable alternative to portland cement on many projects, but its rapid-setting properties make it an ideal solution for today's schedule-and budget-driven projects.
2. Rapid hardening CSA cement (calcium sulphoaluminate)'s main characters are:
Early strength, high strength.
Low alkali content.
Concentrative hydrating heat release.
Adjustable setting time.
Good fluidity.
Frost resistance.
Excellent impermeability.
Excellent corrosion resistance.
