Thermal and Mechanical Properties of Geopolymers Exposed to High Temperature: A Literature Review (2020, background): “Each type of water evaporates at different temperature range; physical water and chemical water evaporate at 20∼100°C and 100∼300°C, respectively, while hydroxyl groups evaporate at temperatures above 300°C [30].”
The effects of ground granulated blast-furnace slag blending with fly ash and activator content on the workability and strength properties of geopolymer concrete cured at ambient temperature (2014, background): “On the other hand, industrial by-product materials such as slag has been shown to release up to 80% less greenhouse gas emissions [3] and there are 80% to 90% less greenhouse gas emissions in the production of fly ash [4].”
Performance of refractory aluminosilicate particle/fiber-reinforced geopolymer composites (2012, background): “A strong relationship between the mechanical performance and the high-temperature shrinkage of MK-based geopolymer systems has been identified [5–7], which means that to better understand the performance exhibited by the composites”
Effects of elevated temperatures on the thermal behavior and mechanical performance of fly ash geopolymer paste, mortar and lightweight concrete (2014, background): “The chemically bonded water evaporates at range of 100–300 C, and finally the dehydroxylation of the OH groups take place at temperatures above 300 C [29,31].”
