The sentences
[ 43 ] found that the fracture toughness of geopolymer concrete was enhanced by basalt fiber, polypropylene fiber, and steel fiber, respectively, and the fracture toughness of geopolymer concrete showed a trend of first increasing and then decreasing with the increase in fiber volume rate, and the specimens containing 0.2% basalt fiber, 0.8% polypropylene fiber, and 1.0% steel fiber have the best reinforcement effect, among which basalt fiber has the best toughening effect.
