Abstract:
Fiber balling is a challenge in scale-up production of ultra-high-performance concrete (UHPC) using conventional concrete mixing practices. Therefore, many producers resort to the use of specialty mixers, and this increases the cost of UHPC. This article presents an investigation into resolving fiber balling issues by adjusting the types, shapes, and sizes of fibers in the mixtures.
