Abstract

The construction sector is seeking sustainable alternatives to reduce CO2 emissions, with cement replacement being a key strategy. Mineralised steel slag is a promising binder due to its reactive CaO and MgO content, enabling CO2 sequestration via accelerated carbonation while maintaining mechanical performance. Incorporating textile waste cotton fibres offers complementary benefits, enhancing flexural strength and potentially increasing CO2 uptake through improved porosity and carbonation pathways. Given the global textile waste surplus and low recycling rates, this approach supports circular economy goals. This study examines composites combining carbonated steel slag with synthetic cotton fibres at three dosages, assessing carbonation uptake and flexural strength under standard curing and wet-dry ageing cycles. Results indicate that fibres promote higher CO2 uptake by creating diffusion channels and improve mechanical behaviour, particularly at higher dosages. Although durability cycles reduce toughness, they enhance environmental performance by facilitating greater carbonation.

Project objectives

La aportación persigue los siguientes objetivos: analizar la influencia de fibras sintéticas de algodón procedentes de residuos textiles en la captación de CO2 de aglutinantes basados en escoria; evaluar el efecto de dichas fibras sobre la resistencia a la flexión de los compuestos; determinar el comportamiento de estos materiales bajo ciclos de envejecimiento húmedo-seco; caracterizar la porosidad y las vías de carbonatación facilitadas por las fibras; investigar la relación entre la dosificación de fibras y la mejora en la captación de CO2 y propiedades mecánicas; y contribuir al desarrollo de soluciones sostenibles que integren residuos textiles en materiales cementantes para promover la economía circular.

Most relevant results

Los resultados más relevantes del estudio indican que la incorporación de fibras sintéticas de algodón textil en aglomerantes a base de escoria mineralizada mejora significativamente la captura de CO2 y la resistencia a la flexión. En primer lugar, las fibras favorecen una mayor absorción de CO2 al crear canales de difusión que facilitan la carbonatación acelerada. En segundo lugar, se observa un aumento en la resistencia a la flexión, especialmente a dosis elevadas de fibras. En tercer lugar, los ciclos de envejecimiento húmedo-seco disminuyen la tenacidad del material, pero simultáneamente potencian la captación de CO2, mejorando el desempeño ambiental de los compuestos. Estos hallazgos subrayan el potencial de esta estrategia para aplicaciones sostenibles en construcción.
