Flexural behavior and microstructure of hybrid basalt textile and steel fiber reinforced alkali-activated slag panels exposed to elevated temperatures

This study investigates the effects of high temperatures and exposure duration on the flexural behavior and microstructure of hybrid basalt textile and steel fiber reinforced alkali-activated slag panels. Three-point bending tests were conducted after heating specimens to 400 °C, 600 °C, and 800 °C for durations of 1 and 2 h. The effects of thermal exposure on the matrix and the basalt fibers from the panels were investigated with scanning...
