- Abstract:
- In order to study the influence of mixing of basalt fiber on crack and deformation of reinforced concrete beams, five test beams were made with the parameters of volume ratio and length of basalt fiber, and the static load tests were carried out. The test data of crack distribution, crack width and midspan deflection of basalt fiber reinforced concrete beams in the process of stress were obtained and compared with common concrete beams. Based on the analysis results of test data, the calculation methods of maximum crack width and short term stiffness of basalt fiber reinforced concrete beams were presented. The results show that the mixing of basalt fiber can effectively prevent cracks extension in reinforced concrete beams and improve the ductility of beams.
