ECC力学性能改良方法对比探究

Engineered cementitions composite contrast to explore mechanical properties improved method

短纤维增强水泥基复合材料(Engineered Cementitious Composite,ECC)是由水泥、粉煤灰、水、细骨料及PVA纤维等材料组成的纤维增强水泥基复合材料,其力学性能及经济生态价值受很多因素影响。国内外诸多学者对ECC中的组成材料进行改进。如调整水分含量、纤维直径、添加外加剂等。通过对比各学者对ECC成分的改进后材料的力学及经济方面的改变的结果做出对比,提出达到改进ECC的不同性能目标时,可对应综合使用的不同的改进方法。

Short fiber reinforced cement matrix composites（Engineered Cementitious Composite,ECC）is composed of cement,fly ash, water,fine aggregates and PVA fiber material of fiber reinforced cement matrix composites,the mechanical properties and economic and ecological value is influenced by many factors.Many scholars at home and abroad of ECC materials composed of improvement.Such as adjusting the water content,fiber diameter,adding admixtures and so on By comparing the scholars to the ECC components of the im-proved material mechanics and the change of the economic aspects of comparison,put forward that to achieve improved ECC different performance objectives,using different improvement methods.
