WebFeb 5, 2009 · 3.1 Hydration kinetics of cement components. In the objective to determine the cement paste properties at early-age, we focus at first on the formation of its microstructure. Partial volumes of the cement paste components are calculated by using the chemical relations of the cement hydration [44, 59] (see Appendix A).The hydration of C 3 S and C … Only well defined and rare natural crystalline minerals can be abbreviated as CSH while extremely variable and poorly ordered phases without well defined stoichiometry, as it is commonly observed in hardened cement paste (HCP), are denoted C-S-H. See more Calcium silicate hydrates (or C-S-H) are the main products of the hydration of Portland cement and are primarily responsible for the strength of cement-based materials. They are the main binding phase ("the … See more C-S-H is a nano sized material with some degree of crystallinity as observed by X-ray diffraction techniques. The underlying atomic structure of … See more When water is added to cement, each of the compounds undergoes hydration and contributes to the final state of the concrete. Only calcium silicates contribute to the strength. Tricalcium silicate is responsible for most of the early strength (first 7 days). … See more • Afwillite – Nesosilicate alteration mineral also sometimes found in hydrated cement paste • Gyrolite – Rare phyllosilicate mineral crystallizing in spherules (a rare mineral from hydrothermal alteration, or an ageing product of alkali-silica reaction) See more WebAn SQ Detector was used for mass spectrometry analysis.
