• Effect of nano-silica on the hydration and microstructure development of Ultra-High Performance Concrete (UHPC) with a low binder amount (2014, background): “As commonly known, the hydrated cement paste subjected to an elevated temperature loses the free water, dehydrates and the hydrated products are transferred [39–44].”
• Colour Change in Heated Concrete (2014, background): “The portlandite decomposition reaction explains the increase in CaO content observed in the cement paste at the temperature of approximately 550 C [17].”

• Development of an eco-friendly Ultra-High Performance Concrete (UHPC) with efficient cement and mineral admixtures uses (2015, background): “curves, it is apparent that there main peaks exist in the vicinity of 105 C, 450 C and 800 C for all the samples, which can be attributed to the evaporation of free water, decomposition of Ca(OH)2 and decomposition of CaCO3, respectively [68–72].”

• Phase transformations and mechanical strength of OPC/Slag pastes submitted to high temperatures (2007, background): “Part of the C-S-H that decomposes contributes to the increase in concentration of calcite and larnite (both remaining throughout the experiments) [7].”
