Preliminary study on the fresh and mechanical properties of UHPC made with recycled UHPC aggregates

[EN] The recycling of construction and demolition waste material reduces disposal of material and also the consumption of resources, therefore promoting sustainability in construction. Ultra-high performance concrete (UHPC) is a relatively new material and its feasibility to be recycled needs to be...

Ultra-high performance concrete (UHPC) is a relatively new material and its feasibility to be recycled needs to be verified. This work investigates the recyclability of UHPC disposed elements, including the production of recycled aggregates and fibres from UHPC. The feasibility of recycled aggregates and fibres at different replacement rates was evaluated through the assessment of rheological and mechanical properties of the newly produced UHPC elements. Concrete mixes with replacement of aggregates at 50% and 100%, displayed compression strength comparable to original UHPC, maintaining the original deflection-hardening response. However, their workability was slightly reduced when increasing the content of the recycled material. Mixes with recycled fibres experienced residual strength losses and behaved as deflection-softening materials in the case of complete replacement.The activity described in this paper has been performed in the framework of the project 'Rethinking coastal defence and Green-energy Service infrastructures through enHancEd-durAbiLity high-performance cement-based materials-ReSHEALience', funded by the European Union Horizon 2020 Research and Innovation Programme under GA No. 760824.Taylor & FrancisDepartamento de Ingeniería de la Construcción y de Proyectos de Ingeniería CivilEscuela Técnica Superior de Ingeniería de Caminos, Canales y PuertosInstituto Universitario de Investigación de Ciencia y Tecnología del HormigónCOMISION DE LAS COMUNIDADES EUROPEARepositorio Institucional de la Universitat Politècnica de València Riunet20222022-11-18journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/191663reponame:RiuNet.
