Abstract

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.

Description

technical field [0001] The invention relates to a novel composite fire-free permeable brick and a preparation method thereof, belonging to the technical field of decorative material applications. Background technique [0002] Foreign countries have studied permeable pavement (Penetrated Pavement) for many years. In the late 1970s, in order to solve the problem of "foundation subsidence caused by pumping groundwater", Japan proposed the "underground restoration policy of rainwater" and started to develop permeable concrete pavement. The relationship between permeability coefficient, porosity and strength of permeable concrete paving materials is studied. In France, experiments on the use of porous concrete as roadside drainage and hard shoulders have been widely carried out. In order to prevent the cement pavement from pumping mud, it is necessary to lay a porous poor concrete base at the joint between the cement slab and the road shoulder. This base can also be used to quick...
