摘　　要：对多种纤维增韧水泥基复合材料(ECC)进行各个龄期立方体抗压强度试验,对比水胶比、胶砂比、粉煤灰及矿渣含量和龄期对ECC力学性能的影响规律,得到ECC早龄期强度的增长规律及各个因素对ECC强度的影响规律。研究结果表明,粉煤灰及矿渣含量、水胶比是ECC抗压强度的主要控制因素。Compressive strength test has been conducted on ECC cubes at different ages.The influence laws of water-binder ratio,sand-binder ratio,fly ash content,slag content,and ages on ECC mechanical properties have been studied by comparison,strength growing laws with the age and how all factors affect mechanical properties of ECC have been figure out.Research shows that fly ash content,slag content and water-binder ratio are the three main strength controlling factors of ECC.

关 键 词：ECC 抗压强度 水胶比 胶砂比 粉煤灰 纤维类型
