Abstract

The invention relates to green waterproof concrete and a preparation method thereof. The green waterproof concrete comprises cement, sand, water, an aqueous emulsion, an aqueous epoxy resin emulsion and modified iron cement, wherein the aqueous emulsion is prepared from acrylic acid, acrylamide, iso-octyl acrylate, methyl methacrylate, water, 2-acrylamide-2 methyl propanesulfonic acid, an SE-10 emulsifier, methylene bisacrylamide, ammonium persulfate and hydroxyl terminated polyether-containing modified polysiloxane through reactions; the aqueous epoxy resin emulsion is prepared from an NPED-20 aqueous epoxy resin, NX-8101 aqueous phenolic amine, water and an aqueous elastomer through reactions; the aqueous elastomer is prepared from iso-octyl acrylate, butyl acrylate, acrylic acid, low-viscosity aliphatic series epoxy acrylate, a 819 photoinitiator, polyethylene glycol (200) dimethacrylate and the SE-10 emulsifier through reactions; the iron cement is prepared from iron mud, a waste polyacrylamide flocculant, a waste polymeric aluminum flocculant and carboxymethylcellulose through reactions. The green waterproof concrete provided by the invention has excellent waterproof and anti-freezing properties.

Description

technical field [0001] The invention relates to the field of concrete, in particular to a green waterproof concrete and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the requirements of people and the country for environmentally friendly high-performance concrete materials continue to increase. Concrete itself has excellent mechanical properties, but there are problems with water resistance and frost resistance deviations in concrete. These defects limit the use of concrete. Application development in related fields. Therefore, the field of concrete calls for researchers in different fields to research and develop waterproof and frost-resistant concrete materials. Because ordinary concrete materials have low requirements on water resistance and frost resistance. Therefore, concrete needs to be improved in terms of high water resistance and frost resistance. Contents of the invention [0003] The...
