Research on Axial Compression Test of CFRP Confined Concrete Column With MPC

In order to solve problems such as aging and non refractory of the traditional organic gum in the concrete reinforcement engineering, the axial compression tests were carried out on the concrete columns which were confined by CFRP with MPC, and compared with the test results of organic glue. The failure mode, stress intensity model and stress-strain law of axial compression test were obtained. The comparison of the results show that when magnesium phosphate cement is used to replace the organic adhesive, the failure mode and stress-strain law of the concrete columns is consistent, and the strength is improved. Moreover, better ductility is got.
