Book excerpt: Those who are working in the manufacture and development of sustainable construction materials need to have a detailed understanding of the many different processes that are available to make sustainable concrete and cement. New Trends in Sustainable Concrete and Cement will enlighten the scientific community on recent developments in this field. Within the volume world-renowned experts summarize recent research findings covering key topics such as: alkali-activated materials using aluminosilicate waste precursors; use of novel cost-effective and eco-efficient supplementary cementitious materials; state of the art characterization techniques and assessment methodologies; advances on the use of biomass ashes, steel slags and waste glass; the role of carbon capture in the production of concrete and mortar; development of eco-efficient composites for specialized applications; recycling of the fine fraction of construction and demolition wastes; and sustainable self-healing concrete. The book will be a valuable reference resource for academic and industrial researchers, civil and structural engineers, manufacturers, and other construction professionals working in the development of sustainable construction materials. - Presents recent developments on eco-efficient cementitious composites - Places an emphasis on complete replacement of cement, with the use of alkali-activated materials - Includes novel enhancing techniques, along with 3D printing and characterization methods
