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.

CSA Cement FAQs

CSA Cement FAQs
  • Q.
    What are the advantages of using CSA Cement?
    A.
    The advantages of using CSA cement is quick setting and high setting.
  • Q.
    What is the color considerations about CSA cement?
    A.
    The color of CSA cement is grayish brown.
  • Q.
    How and when to use set retarders with CSA cements?
    A.
    The retarder for CSA cement is added when mixing the concrete and the adding dosage is 2-5% of the weight of cement.
  • Q.
    What are the difference between rapid set cement and traditional portland cement?
    A.
    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).
  • Q.
    What lead to the low shrinking and strength of CSA Cement based products?
    A.
    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.
