Hydration development of mineral additives blended cement using thermogravimetric analysis (TGA): Methodology of calculating the degree of hydration
TL;DR: In this article, the authors investigated the hydration degree of cement pastes containing blast furnace slag and limestone filler, and proposed a modified thermogravimetric analysis (TGA) method based on the direct estimation of the amount of mineral additives contributing to hydration reactions.

Waste Valorisation using biochar for cement replacement and internal curing in ultra-high performance concrete
TL;DR: In this article, the authors demonstrate the potential of biochar as a mineral additive for cement replacement in ultra-high performance concrete (UHPC), enhancing hydration due to its internal curing and nucleation effects.

Research on cement hydration and hardening with different alkanolamines
TL;DR: In this paper, six types of alkanolamines (TEA, TIPA, DEIPA and EDIPA) were added into Portland cement as chemical additives, and their effects on physical properties and hydration of Portland cement were investigated.
Journal ArticleDOI
Utilization of rice husk ash and waste glass in the production of ternary blended cement mortar composites
TL;DR: In this paper, the authors studied the influence of amorphous silica present in both waste glass and rice husk ash on the performance of ternary blended cement mortars (TBCMs) by a partial substitution of ordinary Portland cement (OPC) with a ratio of 20% waste glass powder (WG) to obtain a blended cement.

Kinetics of Phase Change. I General Theory
TL;DR: In this paper, the theory of phase change is developed with the experimentally supported assumptions that the new phase is nucleated by germ nuclei which already exist in the old phase, and whose number can be altered by previous treatment.

TL;DR: The current state of knowledge of cement hydration mechanisms is reviewed, including the origin of the period of slow reaction in alite and cement, the nature of the acceleration period, the role of calcium sulfate in modifying the reaction rate of tricalcium aluminate, the interactions of silicates and aluminates, and the kinetics of the deceleration period as mentioned in this paper.

The use of thermal analysis in assessing the effect of temperature on a cement paste
TL;DR: 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.
