Understanding silicate hydration from quantitative analyses of hydrating tricalcium silicates
Silicate hydration is prevalent in natural and technological processes, such as, mineral weathering, glass alteration, zeolite syntheses and cement hydration. Tricalcium silicate (Ca3SiO5), the main constituent of Portland cement, is amongst the most reactive silicates in water. Despite its widespread industrial use, the reaction of Ca3SiO5 with water to form calcium-silicate-hydrates (C-S-H) s...
متن کاملHydration of tricalcium silicate in the presence of synthetic calcium–silicate–hydrate
The early age-hydration of tricalcium silicate, the main chemical compound in Portland cement, was studied in the presence of synthetic calcium silicate hydrate (C–S–H) addition having C/S ratios 1⁄4 0.8 and 1.2. Isothermal conduction calorimetry, scanning electron microscopy, differential scanning calorimetry and Si MAS NMR were employed in order to investigate events occurring during various ...
متن کاملProperties of Tricalcium Silicate Sealers.
INTRODUCTION Sealers based on tricalcium silicate cement aim at an interaction of the sealer with the root canal wall, alkalinity with potential antimicrobial activity, and the ability to set in a wet field. The aim of this study was to characterize and investigate the properties of a new tricalcium silicate-based sealer and verify its compliance to ISO 6876 (2012). METHODS A new tricalcium s...
متن کاملA neutron scattering study of the role of diffusion in the hydration of tricalcium silicate
Quasi-elastic neutron scattering was used to monitor the temperature-dependant hydration of tricalcium silicate and Portland cement. Results show that for some samples the degree of hydration is in fact higher at lower curing temperatures. To investigate this effect further, we performed a series of experiments in which samples are initially hydrated at one temperature and then the diffusion pr...
متن کاملQuasielastic and inelastic neutron scattering study of the hydration of monoclinic and triclinic tricalcium silicate
The hydration of Mg-stabilized triclinic and monoclinic tricalcium silicate samples were studied using quasielastic neutron scattering to follow the fixation of hydrogen into the reaction products and by applying hydration models to the data. The quantity of Ca(OH)2 produced during hydration was also determined using inelastic neutron scattering. The monoclinic form was found to be intrinsicall...
