Construction materials could be greener, lighter with clay blend that uses seaweed

Researchers from the University of São Paulo and Federal University of Sao Carlos have developed a method to utilize sargassum seaweed in ceramic clays for construction materials. This innovation not only manages coastal algae waste effectively but also enhances sustainability by reducing the density of clay aggregates while meeting strength requirements. The study highlights significant environmental benefits through life cycle analysis, particularly when using microwave-sintered samples. This new approach offers a promising alternative to traditional expanded clay, improving energy efficiency and material performance.
