TLDR
In this article, the effect of temperature in the mineralogical composition of cement hydration products has been studied using thermogravimetric analysis (TGA) and DTG curves, which can be used to determine fire conditions and the consequent deterioration expected in the cement paste.About:

TL;DR: In this paper, the authors developed complex architectures of cementitious materials using an inverse replica approach where a soft polymer phase emerges as an external conformal coating, and these polymer-coated architected structures display unusual mechanical behavior with considerably higher toughness compared to conventional non-porous structures.

Stabilization and Solidification of Fine Incineration Bottom Ash of Municipal Solid Waste Using Ground Granulated Blast-Furnace Slag
TL;DR: In this paper , the fine incineration bottom ash (IBA) was stabilized/solidified by a green binder, ground granulated blast-furnace slag (GGBS), as a potential subbase material for road construction.
Modeling of heat and mass transfer induced by high temperature in concrete
TL;DR: In this article, the heat and moisture transfer in concrete subject at high temperatures, which causes water movement and pore pressure build up, is represented by a general meso-mechanical model for concrete under mechanical and environmental actions.

Compressive strength of concrete at high temperatures: a reassessment
TL;DR: In this paper, a reassessment of the subject is given, which considers material and environmental factors/mechanisms influencing the strength of concrete during the heat cycle and after cooling, not all of which necessarily result in strength loss.

Thermal stability and decomposition mechanisms of ettringite at <120°C
Q. Zhou,Fredrik P. Glasser +1 more
TL;DR: In this article, the decomposition and reformation of ettringite is studied as a function of water vapour pressure and temperature, and the authors make recommendations for the upper safe service limits for ETTringite-based cements.

Physicochemical, mineralogical, and morphological characteristics of concrete exposed to elevated temperatures
TL;DR: In this paper, the effect of elevated temperatures on the mineralogical changes occurring in the hydrated phases of concrete cubes were studied by measuring ultrasonic pulse velocity (UPV) and consequent deterioration in the compressive strength with increase in temperature.
