Hydrated silicates
WebSynthetic magnesium silicates are white, odorless, finely divided powders formed by the precipitation reaction of water-soluble sodium silicate (water glass) and a water-soluble magnesium salt such as magnesium chloride, magnesium nitrate or magnesium sulfate. WebCalcium 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 glue") in most concrete.Only well defined and rare natural crystalline minerals can be abbreviated as CSH while extremely variable and poorly …
