| Résumé : |
This paper aims to disclose the variation law in the performance of inorganic polymer concrete (IPC) columns under varied temperatures. Therefore, the IPC columns were tested under eccentric compression at several high-temperature conditions, and multiple mechanical indices of each column were measured, including the compressive strength, axial deformation and lateral displacement. On this basis, the author analyzed the impacts of the high-temperature conditions on the mechanical properties of the IPC columns. The analysis shows that the compressive strength of the IPC columns was enhanced with the increase of fire temperature, and started to decline after the temperature surpassed 400 ℃; the loss ratio, i.e. the loss of compressive strength, of each IPC column under eccentric load, was smaller than that of the corresponding ordinary concrete column, under any high-temperature condition. The research results confirm the excellent fire-resistance of the IPC, shedding new light on fire prevention and post-fire evaluation. |
