Effect of Mixing Procedures and Rheology on Fiber Distribution and Mechanical Property of Cementitious Composite (ECC)
摘要
Abstract
Engineered cementitious composite ( ECC) is characterized by high ductility. The processing of fresh ECC plays a key role on fiber distribution and then influences robustness of high ductility of hardened ECC. The effects of fresh ECC mixing procedures and rheological property on fiber distribution were summarized, moreover, the effects of plastic viscosity and yield stress of fresh ECC on ECC fiber distribution and mechanical property were significantly studied. The results show that the fresh ECC mixing procedure with adding fibers finally is the optimal way;good plastic viscosity of fresh ECC leads to fiber uniform distribution, and yield stress is related to fiber distribution and fiber orientation distribution;Good fiber distribution is obtained by adjusting the rheological property, which results in acquiring robust high ductility of hardened ECC.关键词
