Influence of external environment on early-age expansion characteristics of calcium sulfoaluminate cement-based binders

Calcium sulfoaluminate (CSA) cements are widely being promoted as alternative low CO2 binders. CSA cements can also be expansive and designed to be shrinkage-compensating. The main phase of CSA cement is ye’elimite, which hydrates in the presence of calcium sulfate to form ettringite as the main hydration product. The availability of calcium...
