“…Varying reports of geopolymers resistance to ASR have surfaced within the literature (Davidovits 1994;Provis and vanDeventer 2009). Low mortar expansion has been attributed to the fact that alkalis are tied up in the geopolymer framework, and so are not available to react with the silica (Li et al 2006). Those systems with poor performance have been linked to the presence of Ca within the system, which can lead to the formation of expansive ASR gels (Garcia-Lodeiro et al 2007).…”
