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 glue") in most concrete. Only well defined and rare natural crystalline minerals can be abbreviated … 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 … See more C-S-H is a nano sized material with some degree of crystallinity as observed by X-ray diffraction techniques.
