Development and Mechanical Characterization of Dry Fiber-reinforced Concrete for Prefabricated Prestressed Beams

Abstract

In this study, compression, bending and shear properties of the dry fibre reinforced concrete (FRC) were experimentally characterized at its early age. Considering the application of the developed FRC in prefabricated prestressed beams, three-point notched beam bending tests were executed to analyse the post-cracking flexural behaviour, and direct shear tests were performed to evaluate its behaviour shear failure. Furthermore, the consistency of the proposed material on the design has been investigated. Eurocode Standard Specifications for concrete buildings is considered for the purpose of loading and analysing of a prefabricated prestressed FRC beam, which was designed by a cross section layered model for deriving its moment-curvature response. Using the properties of developed dry FRC, the section of the prestressed beam has been suggested.
