Embodiment 1
[0024] Depend on figure 1 As can be seen, a concrete creep test mechanism under corrosion, it comprises the stressed steel plate 5 and the pressure sensor 4 that are installed on the top of the test specimen 6, and the test specimen 6 is installed in the center of the open container filled with the corrosive solution 20; Corrosion solution 20 is provided with conductive metal mesh 18, the steel bar in the test specimen 6 is connected with the positive pole of constant voltage direct current power supply 12, and conductive metal mesh 18 is connected with the negative pole of constant voltage direct current power supply 12, by corrosion solution 20, constant voltage direct current The power supply 12 , the conductive metal mesh 18 and the test piece 6 form an electrochemical corrosion circuit; the dial indicator 14 is installed on the test piece 6 .
[0025] For the convenience of observation, the open container of the present invention includes a bottom tank 15 on which high-st...
Embodiment 2
[0044] Depend on figure 2 It can be seen that the test specimen 6 of the present embodiment 2 is a steel-concrete composite structure, and the steel frame and the concrete are connected by bolts; The surface is uneven, and a glass block 22 is arranged between the measuring head and the concrete part on the top of the test specimen 6 . Because the dial gauge 14 is not installed in the corrosion solution 20, therefore, the dial gauge 14 is not needed to be installed outside the corrosion solution 20 without the installation rod, and the corrosion solution 20 is a sodium sulfate solution of 5% mass fraction.
[0045] The rest are the same as embodiment 1.
