A major barrier to the adoption of Geopolymer concrete in construction is the lack of long-term performance data. Field testing has been undertaken to determine the behaviour of geopolymers in different service environments and address the gaps in knowledge. The University of New South Wales (UNSW Sydney) and Swinburne University of Technology (SUT) undertook field testing at sites to examine durability aspects including carbonation, chloride ingress, reinforcement corrosion and acid attack. This report describes: (1) In- situ testing and core sampling of Geopolymer concrete at four sites across Australia; (2) Long-term performance monitoring of two Geopolymer concrete structures; and (3) In-situ test procedure to investigate the biogenic corrosion of mortar specimens.

Key words: Geopolymer, alkali-activated, binder, concrete, field trails
