Effect of Fibre Apportionment on Flowability of Retrofitting-Fibre-Reinforced Cementitious Composites

Type: conference-paper
Abstract: Concrete is one of the most employed materials on the planet. The integrity of concrete structures may be compromised by flaws that develop during construction or over time, potentially affecting their structural safety. As a result, finding unique repair and retrofit materials has become an important goal for infrastructure research. This study investigates the fresh properties of an unconventional cementitious composite that incorporates a high dosage of steel fibers. The suggested material is intended for use in maintenance and repairs when enhanced protection against severe conditions is required. To determine their static behavior for such applications, four cementitious composite mixtures with different steel fiber contents were created and assessed. The investigation included an experimental flowability test with analytical fiber apportionment evaluation. Findings reveal that all concrete mixtures could flow under their own weight; however, the flowability was generally decreased with increasing fiber content by up to 38.4% relative to that of fibreless concrete. Furthermore, the FSC1 mixture revealed superior apportionment of steel fiber with small fibreless regions relative to that of all other mixtures, which displayed fiber clumping and/or the existence of fibreless regions.
