Abstract

This paper presents a method for calculating the equivalent diameter of fiber in self-compacting fiber reinforced concrete (SCFRC). The key idea is to utilize a small amount of particles with a narrow particle size distribution to replace the fibers by the same volume, without causing any obvious changes of the properties of concrete in both fresh and hardened states. Some test methods, such as slump-flow, V-funnel, air content and compressive strength, were employed to evaluate the properties change of the concrete. The results show that the equivalent diameter of the fiber (L_f/d_f=13 mm/0.2 mm, L_f and d_f means the length and diameter of fiber respectively) is 2.2 mm, which means the fiber can be treated as a type of spherical aggregate with the diameter of 2.2 mm in the application of particle packing-based concrete design models.
