Deformation Recovery of Reinforced Concrete Beams Made With Recycled Coarse Aggregates
Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG ; [Abstract] The purpose of this research is to analyse the long-term deformations of reinforced concrete beams made of recycled coarse aggregates (RCA), using four different replacement ratios, 0%, 20%, 50% and 100%. For said purpose, three different loading stages were carried out: firstly, loading and sustained load for 1300 days, secondly, unloading and recovery where the deformations were registered over a one year period, and lastly, testing the concrete beams up to failure in order to analyse the effect of recycled aggregates on pre-cracked concrete members. The results led to the analysis of deformations under sustained load, as well as those produced after removing the load and the performance of pre-cracked members, while identifying the effect of recycled coarse aggregates on concrete performance in terms of plastic deformation, recoverability and concrete stiffness, and also on structural design. ; The study has been funded by: “CLEAM: Clean, efficient and nice construction along its life cycle” funded by the Centre for the Technology and Industrial Development (CDTI) and led by the Group of Economical Interest CLEAM-CENIT, AIE comprising by the country’s largest construction companies (Acciona, Dragados, Ferrovial, FCC, Isolux Corsán, OHL and Sacyr) and some PYME (Informática 68, Quilosa and Martínez Segovia y asociados). “HACCURACEM: HACCURACEM project (BIA2017-85657-R), funded by the Ministry of Economy, Industry and Competitiveness, State Program for Research, Development and Innovation aimed at the challenges of Society, within the framework of the State Plan for Scientific and Technical Research and Innovation 2013-2016, Call 2017
