SOLUTION FOR INJECTION INTO PRE-STRESSED CABLES AND METHOD OF CABLE INSTALLATION, INCLUDING SUCH SOLUTION Russian patent published in 2025 - IPC C04B12/04 C04B14/10 C04B18/08 E04G21/12 

FIELD: construction.

SUBSTANCE: invention relates to the field of fittings for construction and installation works. Invention contains a geopolymer solution for protecting prestressed reinforcement, a method for producing the geopolymer solution and a method for installing a structural cable. Geopolymer solution contains metakaolin, flue ash and an activator mixture. Activator mixture contains sodium hydroxide and sodium silicate. Molar ratio of Na₂O:SiO₂ in sodium silicate ranges from 0.40 to 0.70. Specific surface area of metakaolin determined by the BET method is greater than or equal to 25 m²/g. Method of producing geopolymer solution includes an activation step, at which metakaolin and flue ash are activated by the action of an activator mixture for polymerisation of the aggregate. Method of installing a structural cable includes the following steps: installing a channel comprising at least one reinforcement structure; reinforcement tension; Injection of geopolymer solution into the channel.

EFFECT: creation of a mortar intended for solving problems arising during setting of a cement or geopolymer mortar.
