Experimental Research on the Anti-crack Performance and Microscopic Mechanism of the Hybrid Fiber Concrete Xiaofan Liu 1,a, Xiaozhou Sheng 1,b, Jixiang Li 1,c, Yunxia Lun 1,d 1College of Civil Engineering and Architecture, Wuhan Polytechnic University, Wuhan, China a hnsfine@163.com, b xiaozhou341@126.com, c lijixiang@whpu.edu.cn, d lunyunxia@whut.edu.cn Keywords: Hybrid Fiber; Concrete; Anti-crack Performance; Microscopic Mechanism Abstract.
While in engineering applications, the mixing amount of fibers are often determined by experience.
The discreteness of the limited experiment results lead to the scarcity of quantitative design in practical engineering.In order to set up the corresponding relation between the fibers’ content and the crack area, sixteen different plat restraint specimens are experimented and analyzed, and the microscopic mechanism of anti-cracking performance is discussed.
