Abstract

The invention provides a concretecorrosive medium transmission inhibiting material. Ahydrophobic component and an embolism component are subjected to a physicochemical reaction to obtain the transmission inhibiting material, the hydrophobic component in the corrosive medium transmission inhibiting material is formed by mixing a hydrophobic component A with a hydrophobic component B by any ratio, the embolism component is selected fromaqueous dispersion liquid of inorganic nanoparticles, and the nanoparticles account for 5-50% of the aqueous dispersion liquid. Concrete compactness is improved, the diffusion coefficient of chloride ion and electric flux of the concrete are reduced, and the mechanical property of the concrete is improved.

Description

technical field [0001] The invention belongs to the field of building materials, and relates to a concrete admixture and a preparation method and application thereof, in particular to a concrete erosive medium transmission inhibiting material for marine concrete. Background technique [0002] Since the 21st century, with the rapid development of the marine economy, marine concrete structures, such as docks, sea-crossing bridges, subsea tunnels, sea airports, and offshore wind power, have become more and more widely used. However, due to the complexity of the marine environment, especially the erosion of various corrosive ions in seawater, the corrosion problem of marine concrete structure engineering has become increasingly prominent, seriously endangering the durability and safety of this engineering facility. [0003] The corrosion damage of marine concrete is mainly due to the close contact between concrete and the external environment, and the external corrosive medium e...
