Adoquines con pigmentos naturales y partículas de desecho: escoria y plástico

Abstract

Abstract: This research seeks to mitigate the environmental impacts resulting from mining for stone aggregates by proposing the use of industrial waste such as steel slag and plastic particles in paving stone manufacturing. To this end, the physical and mechanical properties of the waste materials were evaluated, followed by the design of concrete mixes using the ACI 211.1 method and different levels of substitution, including 30% steel slag as a replacement for coarse aggregate, and 3%, 5%, and 10% PET plastic particles as a partial substitute for fine aggregate. The results showed that the optimal combination of 30% slag and 10% plastic particles increased the compressive strength of the paving stones by 12% compared to those manufactured without recycled materials. The results present a sustainable alternative in construction, allowing the use of recycled materials without compromising the structural performance of the paving stones.
