Paper Title:
Experimental Research on the Fracture Properties of Roller Compacted Steel Fiber Recycled Concrete
  Abstract

Comparative experiments on the ordinary steel fiber recycled concrete (SFRC) and roller compacted SFRC were carried out to research the fracture properties of roller compacted SFRC. The results show that compressive strength, fracture toughness and fracture energy of roller compacted SFRC increase with the increase of fiber volume fraction. Compressive strength increase with the increase of recycled aggregate replacement rate and fracture toughness decrease, however, Crack tip opening displacement has little changes and fracture energy features fluctuation with the replacement ratio of recycled coarse aggregates increasing. The rolled formed layers have significant influence on the fracture properties of SFRC. The fracture toughness of roller compacted SFRC is generally lower than ordinary SFRC and compressive strength is higher than ordinary steel fiber concrete for the same aggregate replacement ratio and fiber volume fraction. Fracture energy of roller compacted SFRC is higher than ordinary SFRC for the higher steel fiber volume ratio.
