Hormigón con Biochar, Materiales Cementicios, Sostenibilidad, Análisis BibliométricoResumen
La búsqueda de alternativas capaces de reducir el impacto ambiental de los materiales cementicios ha intensificado el interés en el biochar como componente funcional en hormigones y morteros. Producido mediante la pirólisis de diversas biomasas, este material rico en carbono presenta una alta porosidad, estabilidad estructural y una composición química favorable para la interacción con matrices cementicias. Estas características han motivado investigaciones sobre su desempeño mecánico, influencia microestructural y contribución a las estrategias de secuestro de carbono. Estudios recientes indican que pequeñas fracciones de biochar pueden modificar los procesos de hidratación, mejorar la zona de transición interfacial y actuar en el refinamiento de la red de poros, resultando en ganancias de resistencia y durabilidad bajo condiciones específicas con parámetros definidos. En paralelo, su incorporación ofrece el potencial de disminuir las emisiones asociadas a la producción de cemento y de agregar valor a los residuos agrícolas, forestales y urbanos. El análisis bibliométrico realizado en la base de datos Scopus destaca la expansión global de este campo de investigación durante la última década, con énfasis en el desempeño mecánico, la sostenibilidad, la microestructura y el secuestro de carbono. La información recopilada permitió comprender las tendencias actuales, identificar limitaciones y señalar direcciones que pueden ser exploradas para el desarrollo de compuestos más eficientes.
