The invention relates to a novel compound burn-
free water permeable
brick and a preparation method thereof. According to the novel compound burn-
free water permeable
brick, the problems of high preparation cost, low strength, poor water tolerance and the like of an existing water permeable
brick are mainly solved. The water permeable brick comprises a
surface layer and a bottom layer, wherein the
surface layer is prepared from super-hydrophilic fibers through mixing,
hot press and maintenance by taking waste
ceramic shattered bone as an aggregate as well as sulphate aluminum
cement and thermosetting resin as bonding materials, and the bottom layer is prepared by adding materials such as water-repellent
powder, water reducing agents,
defoaming agents and interface
enhancer by taking the waste
ceramic shattered bone as the aggregate as well as ordinary
Portland cement as a bonding agent. The preparation method of a
coating layer comprises the steps of uniformly stirring in a certain proportion so as to obtain a mixture, putting the mixture into a forming mold, and carrying out steam maintenance, so as to prepare the burn-
free water permeable brick which has good water permeability and water-retaining property and high strength and is suitable for northeast high and cold areas. Compared with traditional burn-free bricks, the novel compound burn-free water permeable brick has good water permeability and freeze-thaw stability, and a direction is provided for the comprehensive renovation work of environments.
