One reproduced commercial SCC (limestone filler and conventional cement), the others were produced with more sustainable materials: 100% coarse Recycled Concrete Aggregate (RCA) 0%, 50% or 100% fine RCA 45% Ground Granulated Blast-furnace Slag (GGBS) and sustainable aggregate powders such as limestone fines 0/0.5 mm and RCA powder 0/0.5 mm. These aspects can be analyzed through Multi-Criteria Decision-Making (MCDM) algorithms. The benefits of increased sustainability must therefore outweigh any reduction in concrete flowability and strength. Replacing natural raw materials with industrial by-products can increase the sustainability of Self-Compacting Concrete (SCC), although its fresh and hardened behavior will usually worsen. ![]() Finally, recommendations were proposed to provide a guideline for construction materials stakeholders to develop a robust comparative LCA of the concrete, particularly that made with solid wastes. Research gaps and future opportunities were discussed to advance the knowledge of concrete incorporating these solid wastes. The data on four types of solid wastes, including construction and demolition waste, municipal solid waste incineration, tire rubber, and polyethylene terephthalate, were reviewed. A systematic review of previous life cycle assessment (LCA) publications was performed with a focus on outlining the importance of including mechanical and durability properties of such type of concrete in obtaining robust LCA results. The current review article aims to address the dependency between concrete performance and the potential environmental impacts of concrete made with solid wastes. Despite significant advancements, the connecting link between the performance of concrete incorporating solid wastes and its environmental impacts is not fully captured. ![]() Research and practice on concrete incorporating solid wastes have found many advocates in recent years.
