Abstract
- espanolThe continuous research of new functional materials combining both advanced properties and increased sustainability has dramatically risen up in the last decades. Instead of searching for new solutions, composites (formed by a combination of already present materials) are subject of different studies due to their capability of merging the advantages of components. Hence, chitosan, a biowaste-derived biopolymer, has been thermally-converted into chars by pyrolysis treatment. Subsequently, both chitosan and its char are introduced into cementitious matrix forming cement-based composites. The analysis of the mechanical properties of these materials evidenced that char-containing composites show an incipient fracture toughness capability, very appealing for possible structural applications. EnglishLa investigacion continua de nuevos materiales funcionales que combinan propiedades avanzadas y una mayor sostenibilidad ha aumentado dramaticamente en las ultimas decadas. En lugar de buscar nuevas soluciones, los compuestos (formados por una combinacion de materiales ya presentes) estan sujetos a diferentes estudios debido a su capacidad de fusionar las ventajas de los dos componentes. El quitosano, un biopolimero derivado de residuos biologicos, se ha convertido termicamente en carbon mediante tratamiento de pirolisis. Posteriormente, tanto el quitosano como su carbon se introducen en una matriz cementosa que forma compuestos a base de cemento. El analisis de las propiedades mecanicas de estos materiales puso de manifiesto que los compuestos que contienen carbon muestran una incipiente capacidad de resistencia a la fractura, muy atractiva para posibles aplicaciones estructurales.
