Effect of elevated temperatures on geopolymer paste, mortar and concrete
Daniel Kong,Jay Sanjayan +1 more
TL;DR: In this article, the effect of elevated temperature on geopolymer paste, mortar and concrete made using fly ash as a precursor was investigated and it was shown that aggregate sizes larger than 10 mm resulted in good strength performances in both ambient and elevated temperatures.
Journal ArticleDOI
Comparative performance of geopolymers made with metakaolin and fly ash after exposure to elevated temperatures
TL;DR: In this article, the effect of elevated temperatures on geopolymers manufactured using metakaolin and fly ash of various mixture proportions was investigated. And the results showed that the fly ash-based geopolymer has large numbers of small pores which facilitate the escape of moisture when heated, thus causing minimal damage to the polygonal matrix.
