[Abstract]:In order to further promote the research work of fabric reinforced concrete (TRC), which has the characteristics of light weight, high strength, good durability, good reinforcement and crack control, and its practical application in civil engineering, The research progress and application fields of TRC cement-based materials at home and abroad are introduced, and the multi-scale interfacial properties and preparation process of fine concrete and fabric type TRC are described one by one. In this paper, the representative test and theoretical research of TRC are classified and summarized in detail. The development trend and application prospect of TRC are prospected. Finally, some key problems in TRC research and development and related applications are put forward and some suggestions are given that the related experimental research of TRC should be turned to large span space structure, theory and numerical simulation. The mechanical constitutive model of TRC under relative extreme loads is established, and the toughening and strengthening mechanism between fiber fabric and concrete matrix is analyzed theoretically, which provides an important reference for further improving and improving the properties of TRC. Industrial production and application of new TRC materials are realized.
