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 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. WebJun 25, 2024 · The correlation degree of all factors was >0.7, indicating that all four factors significantly affected the strength of FCPB. UCS was the most sensitive to the CTR because the higher binder content led to the increase of CSH gel, ettringite, and other hydration products, which can optimize the pore size and promote the growth of UCS .
WebDec 9, 2024 · Ultra-low humidity environments will lead to changes in the microstructure of C–S–H, which will reduce the mechanical properties and service life of cement-based concrete.
