Calcium silie hydrate - Wikipedia
Preparation Calcium silie hydrate (also shown as C-S-H) is a result of the reaction between the silie phases of Portland cement and water. This reaction typically is expressed as: 2Ca 3 SiO 5 + 7H 2 O → 3CaO · 2SiO 2 · 4H 2 O + 3Ca(OH) 2 + 173.6 kJ The stoichiometry of C-S-H in cement paste is variable and the state of chemically and physically bound water in its structure is not
