The application relates to the field of
cement materials, and particularly discloses a preparation process of a
solid waste-based concrete material resistant to
chloride ion erosion, which comprises the following steps: (1) uniformly mixing
calcium aluminate cement clinker
powder,
sodium borohydride powder, nano-
iron powder,
zinc powder and / or
magnesium powder and
sodium alginate powder, spraying
anhydrous ethanol solution of
polyethylene glycol on the obtained mixed powder, uniformly mixing, heating and
drying, and then
grinding to obtain a slow-release body material; (2) adding the slow-release body material into a
coating liquid, uniformly stirring, and then performing
spray drying to obtain a slow-release anti-
chloride agent; and (3) uniformly stirring a
solid waste-based cementitious component, coarse aggregate, fine aggregate, steel
fiber, the slow-release anti-
chloride agent, a
phosphate rust inhibitor and a water
reducing agent with mixing water to obtain the
solid waste-based concrete material. The application can effectively improve the chloride
ion erosion resistance of a concrete structure, reduce the
corrosion of
metal reinforcers such as steel bars and fibers in the concrete structure, and improve the service life of the concrete structure in a special environment.
