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...

Highlights A method is developed to predict the service stiffness of floor diaphragms in modular buildings. The influence of diaphragm flexibility on the seismic response of modular buildings is presented. Performance-based methods for the seismic design of diaphragm connections in modular buildings are discussed. Abstract

This study investigates the durability of precast fly ash–based geopolymer concrete (GPC) exposed to an outdoor atmospheric environment for 8 years. Core specimens from GPC culverts are tested to determine the effect of carbonation, permeation properties, and poresize distribution, and the durability is compared with...
