Imitated stone environment-friendly concrete road brick and making method thereof
The invention relates to an imitated stone environment-friendly concrete road brick which comprises a surface layer and a base layer. The surface layer comprises, by weight, 5-30% of cement, 70-95% of at least one of quartz sand, granite broken sand and tailing sand and 5-30% of one of ethylene vinyl acetate, acrylic resin and waterborne epoxy resin, and the base layer comprises 3-10% of cement, 0-20% of mineral powder, 0-10% of coal ash, 10-50% of coal ash slag, 10-40% of iron ore dressing bits of 1.0-3.0% in fineness modulus and 35-50% of iron ore dressing bits of 2-10mm in grain diameter. The invention further relates to a making method of the road brick. The making method includes that an original producing, stirring and feeding sequence is adjusted, a binder is completely used to replace water for the surface layer, and a stirring process is improved specially. After a new material is used, feasibility of production links like stirring, material distributing, mould press-forming and demoulding is realized by technical means like changing feeding sequence and increasing stirring time. Compared with conventional surface layer mortar, the new surface layer is higher in flexibility and better in waterproofness, alkali efflorescence of cement products is inhibited, sand is protruding in texture, and the road brick has imitated stone effect integrally.
