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.

Accelerating effects of colloidal nano-silica for beneficial calcium–silicate–hydrate formation in cement
TL;DR: In this paper, the role of water in the hydration process of Ca 3 SiO 5 (C 3 S) cement is investigated, and accelerating effects of adding colloidal silica (CS) are established.

Microstructure of cement paste subject to early carbonation curing
TL;DR: In this article, the effect of early carbonation on performance of paste at different ages was examined by using XRD, TGA, 29 Si NMR, and SEM to understand the mechanism of concrete carbonation at early age through the microstructure development of its cement paste.

Methods for determination of degree of reaction of slag in blended cement pastes
TL;DR: In this article, the degree of reaction of slag in blended pastes is measured using a combination of Selective dissolution and differential scanning calorimetry, but the absolute heat of hydration or contribution to chemical shrinkage of any particular slag is not known.
Journal ArticleDOI
Material properties of portland cement paste with nano-montmorillonite
TL;DR: In this paper, a liquid-form nano-montmorillonite particle with a planar diameter of about 100nm was incorporated into the Portland cement paste at five different dosages and analyzed at four different ages to identify the nanosizing effects on material properties of such cement-based composite.

A review of the application of thermal analysis to cement-admixture systems
TL;DR: The application of thermal analysis in the investigation of the role of chemical admixtures in cement hydration is reviewed in this paper, with or without the presence of accelerators, retarders/water reducers and plasticizers.
