Csh paste
Calcium silicate hydrate (also shown as C-S-H) is a result of the reaction between the silicate phases of Portland cement and water. This reaction typically is expressed as: 2 Ca 3 SiO 5 + 7 H2O → 3 CaO · 2 SiO 2 · 4 H2O + 3 Ca (OH)2 + 173.6 kJ. also written in cement chemist notation, (CCN) as: 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 C-S-H is similar to the naturally occurring … See more When water is added to cement, each of the compounds undergoes hydration and contributes to the final state of the concrete.
