【摘要】：为了进一步推动织物增强混凝土(TRC)这一具有轻质、高强、良好耐久性及良好增强和控裂等特性材料的研究工作及其在土木结构工程中的实际应用,首先介绍了国内外有关TRC水泥基材料的研究进展和应用领域,逐一阐述了精细混凝土及织物类型、TRC的多尺度界面性能、制备工艺,对TRC代表性试验研究和理论研究方面做了详细分类和归纳,并展望了TRC的发展趋势和应用前景。最后提出了TRC研发和相关应用的一些关键性问题和建议:TRC的相关试验研究应转向大跨空间结构和理论及数值模拟方面,建立相关极端荷载条件下TRC的力学本构模型,从理论上分析纤维织物与混凝土基体间的增韧、增强机理,进而为进一步改善和提高TRC性能提供重要参考,实现新型TRC材料的产业化生产及应用。
[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.
