Abstract:
The present invention corresponds to a cement formulation based on sulfoaluminate comprising a specific Ye'elimite crystal proportion having enhanced mechanical resistance, setting and low CO2 emission features. A concrete obtained when mixing said formulation with water and gypsum is further described, having a superior performance at initial ages compared to concrete obtained from Portland cement.
