| 英文摘要 | Reinforced concrete is one of the most widely used materials in engineering construction and reinforced concrete structures can be degraded by CO2 in a humid environment. This article reviews previous studies that investi-gated the evolution of the chemical, structural, and mechanical properties of concrete and steel reinforcement experiencing CO2-induced reaction. The major findings can be summarized as follows: 1) CO2 causes changes in the mineral phases of concrete and steel reinforcement, eventually leading to the deterioration of their structure and strength. 2) Because of the CO2 reaction, the compressive strength of concrete increases first and then de-creases, whereas the tensile strength of the steel reinforcement decreases. 3) The corrosion reaction at the interface (i.e., the interface between soil/rock and concrete or that between concrete and reinforcement steel) causes the interfacial bonding strength to increase first and then decrease. 4) Reinforced concrete degradation caused by high-concentration CO2 is considerably more severe than that caused by atmospheric CO2, and more studies are required to understand the reaction mechanism. |
