Abstract: High-performance mortar and concrete, based on calcium sulfoaluminate cement, were developed. Mortar was designed to present the following strengths: 7 MPa at 5°C within 2 hours, and 15-20 MPa at 20°C within 2 hours. Concrete was designed to present both high workability (slump > 200 mm) for at least 50 minutes, and high early strength (> 40 MPa within 6 hours). The role of different polycarboxylate-based superplasticizers and accelerators (lithium carbonate, calcium hydroxide, and normal portland cement) was studied.
