“…However, the dehydration and breakdown of crystalline hydrates, aggregate types, permeability, and other factors result in a residual strength of ordinary Portland cement (OPC) concrete typically not exceeding 20-30% after exposure to temperatures between 800℃ and 1000℃ [92]. The temperature range of 25-910°C induces structural changes in the cement gels of concrete PENLY and TEMELIN under heat load [93]. Alterations in micro-and mesoporous areas are studied through physical nitrogen adsorption and mercury porosimeter.…”

The imperative to find sustainable alternatives to conventional cement, given its energy-intensive production and significant environmental impact, has driven research into alternative binder materials for civil infrastructure. This paper explores Geopolymer concrete (GPC), a polymer-based binder technology, as a promising solution to reduce the environmental footprint associated with traditional cement production. The study meticulously examines various aspects of GPC, focusing on its impact on crucial durability properties for infrastructure applications. This includes an in-depth analysis of GPC properties, elucidating characteristics influencing performance. In addition to fundamental properties, the paper critically evaluates the resistance of geopolymer pastes and concrete to a spectrum of extreme conditions. The discussion spans testing methodologies for both heat- and ambient-cured geopolymers, providing insights into their performance and durability across diverse environmental challenges. This comprehensive review aims to enhance the understanding of GPC technology, offering valuable insights for researchers, engineers, and industry professionals committed to sustainable and resilient infrastructure solutions.
