Use of a resin mix in concrete, a concrete

By applying resin mixtures, including anion and cation exchange resins, to concrete, the problem of concrete in nuclear industry facilities being susceptible to SO42- and Cl- corrosion has been solved. This has enabled selective adsorption of corrosive ions and improved durability, thus extending the structural lifespan.

Abstract

This invention belongs to the field of concrete technology, specifically relating to the application of a resin mixture in concrete and a type of concrete. This invention provides an application of a resin mixture in concrete, wherein the resin mixture comprises anion exchange resin and a cation exchange resin; the anion exchange resin comprises a quaternary amino anion exchange resin; the cation exchange resin is saturated with sulfonic acid-based cation exchange resin adsorbing Ca. 2+ The results show that applying resin mixtures to concrete can further improve the corrosion resistance of concrete.
