Thermal and Mechanical Properties of Geopolymers Exposed to High Temperature: A Literature Review
Rui He,Nan Dai,Zhenjun Wang +2 more
TL;DR: In this paper, the thermal and mechanical properties of geopolymers at high temperature have attracted great attention from many researchers, however, there are few systematic works concerning these two issues.
Journal ArticleDOI
Effect of phosphoric acid content on the microstructure and compressive strength of phosphoric acid-based metakaolin geopolymers
TL;DR: The results showed that the metakaolin calcined from Kaolinite mainly consisted of quartz crystalline phase and amorphous phase and the diffraction peak for quartz obviously became lower with the increasing of H3PO4/Al2O3 ratios.
