Rather than simply disposing of quarry wastes, these can be used effectively in cementitious composites. This requires a good understanding of their essential properties, micro-scale material characterization methods, and reactivity and function as concrete fillers, as well as the challenge of safety in processing, cleaning and neutralizing hazardous compounds. Seven detailed case studies give very practical examples. The book extends into Life Cycle Assessment, the possibilities of AI-based prediction of the durability of relevant concrete, and economic assessment. This suits academic researchers as well as industry professionals considering sustainable materials and waste management.
