Abstract
The research proposes the development of a sustainable cement composite, obtained by incorporating chemically treated recycled rubber with sodium hydroxide, to reduce the environmental impact of construction. The material valorizes waste from used tires, transformed into an aggregate compatible with the cement matrix through alkaline treatment, leading to improve performance. The properties and expressiveness of the composite support its applicability in sustainable architecture, especially in the creation of prefabricated ventilated facades, modular urban furniture, or decorative elements with variable geometry. The resulting aesthetics contribute to redefining material expression in architecture. The research is conducted within an interdisciplinary framework and is aligned with European strategies on decarbonizing construction and the circular economy.
