Abstract:
Belitic calcium sulfoaluminate cement (BCSA) is a hydraulic, rapid-setting alternative to ordinary portland cement (OPC) with reduced energy demands and CO2 emissions. Currently, limited research exists regarding the structural performance and practical application of BCSA cement concrete, restricting its potential implementation. This talk will cover a study on the flexural performance and behavior of reinforced BCSA concrete beams. Overall, BCSA concrete had similar cracking and loading behavior to the OPC beams. Furthermore, BCSA cement concrete showed increased 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. Additionally, the talk will include some lessons learned about designing concrete mixtures using BCSA cement including some data on the relationship between w/c and compressive strength and the relationship between retarder dosage and setting time.
