A new industry body created to represent the UK manufacturers of Alkali Activated Cementitious Materials (AACMs) that can be specified to reduce the embodied impacts of concrete and improve its durability in some environments. Its intentions are to provide useful and relevant information on AACMs to key stakeholders in construction, represent the manufacturers on Standards bodies, coordinate collaborative research and development between Industry, Academia and Research and Technology Organisations, to create and provide useful resources and access to data on AACMs.
