Abstract

The basalt fiber-reinforced autoclaved aerated concrete (BF/AAC) specimens were prepared and the corresponding fracture performance were investigated in this study. The relationship curve of load and displacement were obtained and then the crack initiation load and ultimate load were determined. Then the fracture toughness calculated according to double-K fracture model and the fracture energy were calculated. The results show that as the basalt fiber (BF) content grows, the bending degree of macro crack path on the fracture surface increases slightly, while the fracture toughness and the fracture energy increase to varying degrees. When the BF content is 0.4%, the specimen shows the best fracture performance, and the corresponding initiation toughness, fracture toughness, and fracture energy increase by 43.34%, 86.66%, and 117.75%, respectively. In addition, the microscopic morphology of BF/AAC sample was observed. The SEM results show that BF can bridge micro crack in AAC matrix.
