What is the Development Bottleneck of Alkali-Activated Binder

Alkali-activated binder is considered as one of green environmental low-carbon cementitious materials. However, this binder has not been produced commercially and used widely in civil engineering so far. Based on the analysis on the keynote reports on alkali-activated binder in International Conferences on Cement Chemistry, recent work on alkali-activated binder focus on its composition, microstructure of hardened paste and properties. There is a lack of work on building elements and structure made with this binder. This issue hinders the establishment of technical standard system of alkali-activated binder and related design norm of building structure. This could result in a great barrier of the commercial production of alkali-activated binder. As a result, it is rather difficult to enhance the application of alkali-activated binder.
