Abstract: In order to study the reinforced function of the basalt fiber reinforced concrete compression members and to promote the application of basalt fiber, the optimal length of fiber was obtained by adding five basalt fiber concrete with 0.1% volume fraction.12 mm basalt fiber on the strength of the concrete cube reinforcing the best effect;followed by the choice of 12 mm and 24 mm of the two basalt fiber reinforced concrete the best amount to study the best dosage range is 0.15%.Finally, three basalt fiber short columns were made with 0.15% volume fraction, 12 mm length and 24 mm length basalt fiber concrete respectively.Three columns of ordinary reinforced concrete short columns were made and the axial compression limit of all test columns was made.The results show that the bearing capacity of reinforced concrete short columns with basalt fibers increases by 28% compared with ordinary reinforced concrete columns.Basalt fiber improves the ductility of reinforced concrete short columns.In addition, the bearing capacity of axially loaded columns of reinforced concrete short columns with basalt fiber is larger than the calculated value, indicating that basalt fiber not only improves the compressive strength of concrete, but also enhances the performance of reinforced concrete and concrete.
