Alkali-activated cements, including ‘geopolymer’ materials, are now reaching commercial uptake in various parts of the world, providing the opportunity to produce concretes of good performance and with reduced environmental footprint compared to established technologies. The development of performance-based specifications for alkali-activated cements and concretes is ongoing in several jurisdictions. However, the technical rigour, and thus practical value, of a performance-based approach to specification of novel cements and concretes will inevitably depend on the availability of appropriate, reliable testing methods, particularly regarding key aspects of durability where degradation mechanisms may be complex and depend on the chemistry and microstructure of the binder. This paper will briefly discuss the activities of RILEM Technical Committee 247-DTA in working to validate durability testing standards for alkali-activated materials, bringing scientific insight into the development of appropriate specifications for these materials.
