摘　　要：ECC是Engineered Cementitious Composites的简称,是一种具有超强韧性的乱向分布短纤维增强水泥基复合材料。ECC是一种经细观力学设计的先进材料,具有应变-硬化特性,在纤维体积掺量为2%左右的情况下,其极限拉应变通常能达到3%以上。ECC具有的优良特性使其能广泛应用于土木工程的众多领域。In this paper,ECC(engineered cementitious composites) is one of the fiber reinforced cementitious composites,which shows pseudostrain hardening behavior with several percent tensile strain.When the ECC contains about 2% of PVA fibers,the ultimate tensile strain of ECC is more than 3%,which is 300 times greater than that of concrete.So,the ECC has been wildly applied to a lot of fields in civil engineering.
