摘要

This paper presents four innovative utilizations of calcium sulfoaluminate (CSA) cement: - development of concrete with high early strength: 40 MPa, 6 h after its preparation, and higher than 55 MPa after 24 h, - design of self-leveling screed with limited curling, when unbonded to its support, - design of self-leveling topping mortar presenting the following properties: time of workability higher than 30 mm, set within 75 mm, and low drying shrinkage (<250 (mu)m/m). - glass-fiber-reinforced cement (GFRC) composites that can be demolded 4 h after casting and present high ductility and durability after aging in different weathering conditions.
