Abstract: Sustainability within the building industry has been much debated, as the production of building materials, the erection of structures and their use is a major source of environmental impact. The production of the concrete constituent material cement alone is responsible for a substantial share of global anthropogenic carbon dioxide emissions. Green concretes with reduced cement content may provide a feasible alternative for improving concrete sustainability independently of supplementary cementitious materials. For this purpose, cement-reduced, green concrete is developed by a design process centred on packing optimization of the granular mix constituents, nearly reducing the cement content by two thirds. The results indicate that the concretes developed with the presented concrete design algorithm have a high level of technical performance, but still show deficits in workability. As the sustainability of concrete is not only a function of absolute technical performance and environmental impact, the durability of these new concretes must also be thoroughly scrutinized.
