Self-compacting steel fibre reinforced concrete for precasted sandwich panels : experimental and numerical research

摘要

In Portugal, steel fibres are the most used for concrete reinforcement, and flooring and tunnelling are the mainapplications of fibre reinforced concrete (FRC). In last years the prefabrication industry is showing more interest in collaborating inFRC research projects. The research carried out in consortium by University of Minho (UM) and two private companies for thedevelopment of self-compacting steel fibre reinforced concrete (SCSFRC) is an example of this new strategy. This research has thefollowing main tasks: conceive a rational mix design method; evaluate the most relevant material properties and the structuralbehaviour of laminar elements; develop numerical tools. This paper intends to show the research strategy adopted in the SCSFRCproject, since it is a typical example of the methodology followed by the UM research group, the most active in Portugal, in the FRCdomain.
