Abstract:
Belitic calcium sulfoaluminate cement (BCSA) is a hydraulic, rapid-setting alternative to ordinary portland cement (OPC) with reduced energy demands and CO2 emissions. BCSA cement has numerous current and potential applications, including transportation repair and precast manufacturing. Currently, limited research exists regarding the structural performance of BCSA cement concrete, restricting its potential implementation. Thus, the purpose of this research is to provide insight into the flexural performance and behavior of reinforced BCSA concrete beams. Overall, BCSA concrete had similar cracking and loading behavior to the OPC beams, with increased moment capacity for compression-controlled specimens. Furthermore, BCSA cement concrete showed increased tensile strength and ductility when compared to OPC. Overall, the flexural strength of the BCSA cement concrete was higher than the control OPC concrete and the predicted flexural strength based on compressive strength, indicating the current flexural strength equations are applicable for BCSA reinforced concrete design.
