Abstract

The invention belongs to the building material technology field, specially relates to a method for preparing a ceramic permeable brick comprising the following steps: 1) preparation of the bottom blank: crushing the solid waste clinkers and screening the same into coarse grains with a grain size of 2-3mm to get coarse grain solid waste clinkers, wherein the weight percentage of each component is as follows: 60-80% of coarse grain solid waste clinkers, 20-40% of cascade high temperature binders which pass through a 100 mesh screen; choosing the coarse grain solid waste clinkers and the cascade high temperature binders which pass through a 100 mesh screen for stand; sealing and staling the mixture by plastic clothing to get the bottom blank; 2) preparation of the surface course blank: crushing the solid waste clinkers, screening the same into fine grains with a grain size less than 2mm and more than or equal to 1mm; 3) moulding by means of hydraulic press machine of brick; 4) drying the permeable brick green body; 5) calcining the dried permeable brick green body by a silicon carbide bar furnace or a fuel gas shuttle kiln at 1100-1200 DEG C to get the environmental ceramic permeable brick products. The ceramic permeable brick has advantages of high intension and low cost.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a preparation method of ceramic permeable bricks. Background technique [0002] Permeable brick is a new type of building material used in urban construction. It is laid in urban roads and squares, which is conducive to improving the ecological environment of the city and avoiding the "heat island" phenomenon. Permeable bricks are generally divided into two types: unfired permeable bricks and sintered permeable bricks. Non-fired permeable bricks are mainly made of adhesive materials such as cement and lime mixed with clinker such as sand and stone and steel slag, and are made by molding, autoclaving and other processes, such as Sun Zhonglu's invention patent - manufacturing method of permeable bricks (public number CN1528700) and Ni Wen's invention patent - a kind of preparation and use method of steel slag colored pavement brick with water permeable funct...
