(1) Basalt fibers had a significant effect on the fracture behavior of the FAGC samples. The descending segment of the load-CMOD curves of basalt fiber–reinforced FAGC dropped more slowly than that of plain FAGC. Basalt fibers promoted the elastic modulus of FAGC, whereas basalt fiber–reinforced FAGC manifested the maximum peak load of 1480 N.
