超高延性水泥基复合材料耐久性研究进展
Research progress on durability of ultra-high engineered cementitious composites
摘要
Abstract
Ordinary concrete is prone to face performance degradation and insufficient durability in special environments.Ultra-high engineered cementitious composites(ECC)is a kind of fiber reinforced cement composite material.It has strain hardening and self-healing ability after microcracks formation under tensile load,which makes ECC possess better durability than ordinary concrete under various environmental conditions.In this paper,the research progress of ECC durability at home and abroad in re-cent years was reviewed.The characteristics of impermeability,frost resistance,chemical corrosion resistance,high temperature re-sistance and wear resistance of ECC were summarized and compared with ordinary concrete.It was found that studies on the dura-bility under the condition of multi-factor coupling,the interpretation in term of micro level of durability,and the design of ECC with high temperature resistance and good wear resistance were not sufficient.Based on this,several research directions in the fu-ture were put forward.关键词
