Abstract: Life Cycle Analysis has shown that Alkali Activated Material (AAM) binder can reduce carbon emissions, compared to OPC cement, by at least 80%. One of the main barriers to adoption of AAM is the lack of control over the supply chain of source materials such as fly ash and blast furnace slag. An understanding of market dynamics and the industry value chain is required to push AAM into the well established and conservative construction market. Another barrier is the fact that most concrete standards have been developed on the basic premise that OPC cement will be used. A related issue is the testing protocols for durability, which may or may not suit AAM concrete. Unlike OPC, a long in-service track record of AAM is absent. Consequently, research and theoretical insight must be used instead to justify the validity of applying existing or modified durability testing methodology to AAM concrete.
