Abstract
In this study, a novel TiO2-graphene modified epoxy resin employed as coatings for ordinary Portland cement (OPC) concrete was for the first time fabricated with three different dosages. It was found that the TiO2-graphene could be dispersed homogeneously in the epoxy resin matrix without reducing interfacial bonding strengths between coatings and OPC concrete substrates. Moreover, with the aid of certain dosages of TiO2-graphene nanofiller (0.3 % and 0.5 %), both the impermeability towards water and chloride of the OPC concrete reflected by capillary sorptivity and chloride penetration respectively was greatly improved compared to the pure epoxy resin coated concrete or concrete substrate w..
