| titleOfInvention | Hardening acceleration/hardening retardation composition for building materials |
| abstract | Provided herein are compositions for use as hardening modifiers, such as hardening accelerators or hardening retarders, for building materials, and methods for their production. The composition is characterized by a two-phase nature in which solid calcium silicate nanoparticles are dispersed in an aqueous solution containing inorganic water-soluble iron and possibly zinc, silicate and calcium. Additional components may be present, such as inorganic ions and silica nanoparticles. Depending on the relative proportions of the components, the compositions can be used to retard or accelerate the hardening process of building materials, such as cement or concrete. The building material thus obtained further exhibits an enhanced strength upon application of a compressive force thereon. |
