Abstract:
Belite calcium sulfoaluminate cement (BCSA) has been used in non-structural rapid repair applications over the last 40 years due to its desirable properties such as: high early strength, low shrinkage, and low carbon emissions. ACI 318-19 allows the use of alternative cement concrete in structural applications if they meet or exceed design criteria for portland cement concrete. One such criterion is the stress-strain behavior of flexural members. To further investigate this property for BCSA concrete, flexural compression specimens were fabricated and tested in combined axial compression and flexural loading scenario as shown in Figure 1. Results were used to determine the rectangular stress block parameters for BCSA concrete flexural members and were compared with historical portland cement concrete data. The ACI 318-19 estimation of flexural design parameters were found to be adequate and conservative when applied to BCSA concrete members. This research is a finished ACI CRC funded project overseen by ACI 242 Alternative Cements Committee.
