纤维混凝土(FRC)对混凝土结构的耐久性有明显加强的作用,可以通过延长建筑物的使用寿命,节约建筑物维护和维修的费用.探讨一种新型的聚合物合成纤维水泥基复合材料ECC的工作性能和应用现状.大量研究表明PVA纤维混凝土可以通过牺牲部分抗压强度来提高材料抗裂性能.因此,如果在工程施工中,梁、板等受拉构件或者混凝土钢筋保护层等需要进行耐久性设计的构件使用ECC材料,会取得显著的抗裂性能,提高混凝土构件的耐久性,而以抗压强度起主要作用的抗压构件则建议谨慎使用.
纖維混凝土(FRC)對混凝土結構的耐久性有明顯加彊的作用,可以通過延長建築物的使用壽命,節約建築物維護和維脩的費用.探討一種新型的聚閤物閤成纖維水泥基複閤材料ECC的工作性能和應用現狀.大量研究錶明PVA纖維混凝土可以通過犧牲部分抗壓彊度來提高材料抗裂性能.因此,如果在工程施工中,樑、闆等受拉構件或者混凝土鋼觔保護層等需要進行耐久性設計的構件使用ECC材料,會取得顯著的抗裂性能,提高混凝土構件的耐久性,而以抗壓彊度起主要作用的抗壓構件則建議謹慎使用.

As a new type construction material, fiber reinforced concrete (FRC) is accomplished to improve the durability of concrete structures. The repairing costs are saved by prolonging the service life of buildings. This paper investigates the working mechanism and application situations of a new type polymer fiber reinforced concrete, namely engineered cement based composite (ECC). Many research reports indicate that the ductility of PVA fiber reinforced concrete can be improved by the damage of compression strength. Therefore, polymer fiber reinforced concrete is suitable to be used in the reinforcement covers and tension components including beams and slabs. However, the present investigation suggests that the use of polymer fiber reinforced concrete in compression elements should be cautious.
