| Abstract |
This paper investigates the potential application of red ceramic waste as supplementary cementitious materials in structural concrete as a strategy to implement a circular economy in the Brazilian construction industry from a sustainable infrastructure perspective. The experimental program comprehends the waste characterization and application in concrete mixtures produced with different w/b (0.35, 0.45, and 0.55) and Portland cement replacement (5%, 10%, 20%, and 40%). Eco-efficiency intensity indicators considering cement consumption, carbon dioxide emission, and embodied energy complement the structural concrete assessment. Concrete mixtures with up to 40% of waste, combined with w/b 0.35 and 0.45, did not compromise the concrete structural performance regarding compressive strength. The relatively low water absorption in concrete mixtures produced with up to 40% Portland replacement by red ceramic waste suggests concrete ability to restrain water and vapor ingress on a satisfactory level. Structural concrete with Portland cement replacement by 20% or 40% of waste showed better performance from the eco-efficiency perspective. Structural concrete with Portland cement replacement by 20% or 40% of waste can preserve mechanical properties, reduce carbon dioxide release, and implement a circular economy in the construction industry. |
