Use of Construction Waste to Replace Conventional Aggregate in Reinforced Concrete Production
The work aims to study the influence of using construction and demolition waste (CDW) in replacing coarse and fine aggregate in the production of concrete and its impact on hardened concrete properties. To compare and analysis its behavior a moderate compressive strength concrete was used as a benchmark. Compressive and splitting tests were performed using 120 cylindrical concrete specimens with 150 mm diameter and 300 mm length. Additionally, reference and RAC concrete beams were prepared and tested under four points loaded scheme to investigate the mechanical response on both maximum load capacity, displacements and also evaluate the flexural strengths of the beams tested. Results obtained showed to be a good solution for an adequate destination to the CDW from the construction industry and the full recycled fine aggregate replacement exhibited better performance in all tests performed proving, this way, great potentialities to be used as fine aggregate in concrete production.
