متن کاملUnderstanding 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 کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
Effects of D2O and Mixing on the Early Hydration Kinetics of Tricalcium Silicate
The hydration of tricalcium silicate powder with H2O and D2O was followed at three different temperatures using isothermal calorimetry. For both types of paste, the early kinetics could be accurately modeled, from the time of mixing to a point on the downslope of the main hydration peak, with a four-parameter nucleation and growth model. Pastes made with D2O followed the same reaction path as p...
