    Abstract: 高韌性纖維混凝土(Engineered Cementitious Composites,簡稱ECC)是經由微觀力學設計的水泥基工程複合材料,是在基體中添加聚乙烯醇纖維(polyvinyl alcohol,簡稱PVA),在拉力和撓曲作用下呈現高延展性,具有應變硬化和多重開裂的特性。
    ;Engineered Cementitious Composites (ECC) is a material using polyvinyl alcohol (PVA) fibers in the matrix. The most important performance characteristic of ECC is that it can exhibit multiple cracks and strain-hardening under tensile and flexural behavior.
    In this study, the content of fly ash, PVA fiber and expansive agent are used to investigate ECC’s characteristics. Including drying shrinkage test, autogenous shrinkage test, uniaxial Compressive test, uniaxial tensile test and four points flexural test. The result shows that drying shrinkage increase and autogenous shrinkage decrease while the more content of fly ash in ECC. The more fiber content in ECC cause drying shrinkage and autogenous shrinkage increase. Among all proportions with expansive agent. The specimen adding 0.5% of expansive agent has the lowest drying shrinkage and autogenous shrinkage.
