CSA Cement
CSA (Calcium Sulfoaluminate Cement) cement is a special cement used in many applications where early high strength and fast setting development are necessary. CSA cement is short for Calcium Sulfoaluminate Cement, also named rapid setting cement, high strength cement, fast hardening cement, CSA type III and CSA binder. If you are looking for trusted calcium sulfoaluminate cement suppliers, we have various types of CSA cement available. Feel free to contact us for CSA cement price, we are ready to offer our service for your project.

CSA Cement Application
01
CSA Cement Application in Make Prefabricated Component
Because the strength of CSA cement plays a 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
04
CSA Cement Application in Winter Construction Concrete
CSA Cement has been widely used in winter construction of building construction since the 1970s in China.
05
CSA Cement Application in Solidify Harmful and Toxic Wastes
It has special effect on the consolidation of harmful wastes and is suitable for the solidification of harmful and toxic wastes.
06
CSA Cement Application in Make GRC Product
Hydration slurry PH of low alkali CSA cement is less than 10.5, which is especially suitable for glass fiber products (GRC).
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 cementis 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 cementis 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.
