CSA Cement
CSA (Calcium Sulphoaluminate Cement) cement is a special cement used in many applications where early high strength and fast setting development are necessary. CSA cementis short for Calcium Sulfoaluminate Cement, also named rapid setting cement, high strength cement, fast hardening cement, CSA type III and CSA binder.

CSA Cement Application
01
CSA Cement Application in Make Prefabricated Component
Because the strength of cement csaplaysa fast role, the application of CSA cement in prefabricated components can save the energy cost of steaming and curing.
02
CSA Cement Application in Rush Repair And Rush Construction Project
CSA cement has the characteristics of early strength and high strength. Its 3-day strength is equivalent to 28-day strength of Portland cement with the same grade. It is suitable for rush repair and construction projects.
03
CSA Cement Application in Marine Construction Engineering
CSA cement's impermeability and seawater corrosion resistance are much better than Portland cement. It is suitable for marine construction engineering
CSA Cement FAQs
The advantages of using CSA cement is quick setting and high setting.
The color of CSA cement is grayish brown.
The retarder for CSA cement is added when mixing the concrete and the adding dosage is 2-5% of the weight of cement.
The main difference is that the setting time. Generally, the setting time of calcium sulphoaluminate cement is 10-60 minutes, while that of ordinary Portland cement is 60-300 minutes. The compressive strength is different. Calcium sulphoaluminate cement is generally above 35 MPa a day, while ordinary Portland cement has no standard requirement (too low).
One factor contributes to that is its high water demand for properly hydration. Another is that the CSA Cement,once in contact with water,will immediately begin to produce Ettringite which can fill the pores of the cement matrix, making material denser.
