定向钢纤维混凝土的制备方法以及断裂性能研究进展
Review on Preparation Methods and Fracture Properties of Aligned Steel Fiber Reinforced Concrete
摘要
Abstract
This paper systematically elaborated the preparation method,fiber distribution characteristics,and fracture properties of directed steel fiber reinforced concrete(ASFRC)in combination with research achievements in recent years.It compared and introduced the characteristics and applicability of different methods for preparing ASFRC.By summarizing varieties of methods for determining the parameters to describe the distribution characteristics of steel fibers,it discussed the influence of different factors on the distribution of steel fibers in detail.Referring to the test method and technical standard of ASFRC fracture performance,it compared different fracture indices obtained from bending fracture tests and results.Meanwhile,it summarized the influencing factors and fracture simulation based on the existing research on the fracture properties of ASFRC.Finally,it prospected the possible research directions of ASFRC.关键词
