Calcium sulfoaluminate (CSA) cement is a specialty hydraulic binder primarily composed of calcium sulfoaluminate minerals. This type of cement was developed to address specific needs in construction that ordinary Portland cement (OPC) could not meet, such as rapid strength gain, reduced shrinkage, and lower carbon emissions. The distinct feature of CSA cement is its rapid set time, which can achieve significant strength in as little as 3–6 h, compared to days or weeks for OPC. This property makes it ideal for urgent repair works and applications where speed of construction is critical. Moreover, CSA cement’s resistance to sulfate attack and low alkalinity make it particularly effective in severe environmental conditions, such as in marine environments or soil with high sulfate content.
