Rapid industrial growth has witnessed the ever-increasing utilization of sand from rivers for various construction purposes, which has caused disruption to natural ecosystems. Sustainable Construction Materials: Recycled Spent Garnet presents an investigation into the capacity for these minerals to serve as a sand replacement and as a viable, sustainable construction material to help mitigate the current rate of exploitation of river sand. Features: Presents the effects of spent garnet on the fresh and hardened characteristics of self-compacting geopolymer concrete in terms of workability and mechanical strength. Examines spent garnet with regard to concrete durability in response to carbonation, as well as sulphate and acid attack. Includes a comprehensive review of the existing literature in the field, including past developments in self-compacting geopolymer concrete, as well as the ongoing activities in the field of spent garnet-based concrete production.
