Fibre-Reinforced Concrete Is Sustainable and Cost-Effective for Water-Retaining Structures

Although fibre-reinforced-concrete (FRC) is increasingly used, it has been occasionally applied to water-retaining structures (WRSs), and no comprehensive design guidelines are currently available for the of WRSs with FRC. A methodology such applications based on recommendations research three reference scenarios representing a wide range WRSs: flood defence wall, weir swimming pool wall. For each these scenarios, alternative designs using different FRC mix have compared through statistical analysis several relevant parameters. This study confirms that use significantly reduces reinforcement requirements when conventional reinforced concrete solutions. Clear trends identified between structural performance resulting WRS designs, characteristics fibre type dimensions. considered not only but also total cost environmental footprint per unit length WRSs, considerations further case adoption in applications. Overall, dosages below 0.75% 2% volume steel synthetic fibres, respectively, can lead lower carbon than their counterparts.
