In recent years, people have paid more and more attention to intelligently responsed materials. The rapid development of building materials and construction technology also promotes the development of concrete towards intelligent direction, which makes the research of damage-responsive concrete a hotspot in the field of intelligent materials. With the advent of the advanced stage of the development of concrete materials, the structural design of the force field damage intelligently response fiber concrete is becoming increasingly ingenious. Its research technology is more and more advanced, the research method is optimized rapidly, and the application prospect is quite broad. Therefore, it is necessary to study the response design, response mechanism, intelligent monitoring and intelligent repair of the intelligent response fiber concrete with force field damage. At present, embedded sensors and surface mounted sensors are mainly used in concrete monitoring. They have disadvantages such as low sensitivity, no real-time monitoring, complicated operating procedures, time-consuming calibration, high cost, and embedded sensors will have a negative impact on concrete. On the contrary, the intelligent component (fiber) in intelligent fiber concrete is a component of the concrete itself, and the addition of fiber will increase the strength of the concrete. Moreover, intelligent fiber concrete has self-sensing and self-repairing capabilities, which can significantly improve the safety and durability of concrete. In terms of the types of intelligent components, the intelligent characteristics of carbon fiber, optical fiber, hollow glass fiber, and various nano-fiber have been studied in recent years. In the aspect of intelligent design, in recent years, the focus has been carried out on the self-perceived design and self-repair design of force field damage. In terms of intelligence monitoring, a large number of studies have revealed the contribution of power loss, light wave changes, and resistivity changes to intelligence. In terms of the research of intelligent response mechanism, in recent years, the response mechanism of various types of intelligent fiber concrete in the micro scale and macro scale has been mainly clarified. Studies have shown that the intelligent response to force field damage fiber concrete has high response sensitivity, can respond to weak stress and other parameters in time, and is of great significance to the intelligent real-time non-destructive detection of concrete materials. This paper reviews the research progress on the force field damage response, monitoring and repair of intelligent fiber concrete. The design progress of damage response design and repair design of fiber reinforced concrete are summarized. What is more, the research progress of monitoring electric signals and optical signals of smart fiber concrete in response to force field damage is introduced. This paper focuses on the research progress of the mechanism of damage response of carbon fiber, optical fiber, glass fiber and nano-fiber smart fiber concrete. And the existing force field damage intelligent response fiber concrete is compared and analyzed, in addition, the current problems of the intelligent response fiber concrete are pointed out and its development prospect is prospected. It is of guiding significance for the future research on force field damage intelligent response fiber concrete. © 2021, Materials Review Magazine. All right reserved.
