The red brick imitating furring brick is produced by cutting red brick into thin brick of certain thickness, and the thin brick has smooth surface and high water absorption, and thus has poor construction performance, poor wall adhesion and easy falling off; meanwhile, the defective rate in cutting is high, and a large amount of waste water and waste residues are generated. In addition, the color and luster of the red bricks, internal defects, etc. can affect the yield and quality of such thin bricks. The red brick-imitated furring brick is also derived from a red brick-imitated ceramic brick, belongs to a derivative of a ceramic wall tile, has good product performance, but has different raw materials and firing processes, is greatly different from the traditional red brick in texture, cannot achieve the aesthetic feeling of the traditional red brick building, has higher price, and has larger difference between the color of the brick and the color of the red brick. Some imitated grey brick furring bricks are also available in the market, but most of the furring bricks are mainly cement-based products, and the texture and the color of the grey bricks cannot be achieved.
At present, in the field of building materials, although a large amount of wastes do not have proper treatment and utilization channels, not all solid wastes can be directly used for preparing the red brick-imitated wall tile, and like the requirement of red bricks on raw materials, the contents of elements such as K, Na, Ca, Mg, S, Cl and the like in a mixture are comprehensively controlled to prevent the phenomena of lime burst, frost return, expansion and the like when meeting water; meanwhile, the content of organic matters is controlled to reduce the influence on the construction performance of the inorganic binder and the influence on the fineness of the surface of the brick during adhesion; certain plasticity is ensured to facilitate molding. The soil deposited in the delta area, the yellow river sludge, the bauxite tailings and the like meet the conditions, but the components need to be adjusted.
In conclusion, the preparation method of the red-brick-imitated furring brick which is similar to a red brick in texture and color and good in bonding property is provided, can be used for indoor and outdoor architectural decoration, and is a problem worthy of research.
