Summary: The production of alkali-activated (AA) binders uses less energy and produces less carbon dioxide than conventional Portland cement (PC). These binders can also offer the concrete producer flexibility in raw materials sourcing and the opportunity to produce concrete products without using conventional cements. Although low-carbon concretes made from AA binders share some materials in common with conventional PC-based concretes, there are some significant differences in the supply chains and business models that apply to their manufacture and sale. This paper summarises the current position in this emerging area of construction technology.
