Problems solved by technology

It is not difficult to see that the high-temperature binder used in the prior art is directly introduced in the form of a solid state, and the mixing of the high-temperature binder and the aggregate of the permeable brick is a mixture between two solid phases, which is difficult to mix evenly, thus It is easy to cause shortcomings such as unstable product quality, which restricts the improvement of the quality of ceramic permeable bricks

[0030] Preparation of ceramsite: Put the secondary sedimentation sludge in a sludge dehydrator for 30 minutes, put it in an oven, heat it up to 70°C, and dry it for 4 hours to obtain dewatered sludge. Dehydrated sludge, kaolin and calcite Mix at a ratio of 4:3:2, place it in a ball mill for 3 hours, and pass through a 200-mesh sieve to obtain dry ceramsite material;

[0031] Disperse 2kg of the above-mentioned ceramsite dry material in 700mL of sodium silicate nonahydrate solution with a mass fraction of 20% to obtain a mud cake, put it into a ball making machine to make raw meal balls with a particle size of 2mm, and place the raw meal balls in In an oven with a set temperature of 100°C, dry for 2 hours, put it into a muffle furnace after drying, heat up to 400°C, preheat for 10 minutes, then heat up to 1100°C, bake for 15 minutes, stop heating, and cool to room temperature naturally. The material is discharged to obtain ceramsite.

Abstract

The invention discloses a method for producing a water-permeable ceramic brick, and belongs to the technical field of building materials. Quicklime reacts with water to form calcium hydroxide, and thecalcium hydroxide reacts with sulfates in manganese slag to form dihydrate gypsum, and the gypsum has a good gel property, and can agglomerate particulate matters in the water-permeable ceramic bricktogether to make the water-permeable ceramic brick have a high strength; ceramsite is produced from dehydrated sludge, kaolin and calcite, the ceramsite is mixed into cement to form the water-permeable ceramic brick, the cement in the produced water-permeable ceramic brick is covered with ceramsite particles, and the ceramsite is a material containing a large number of pores inside and improves the strength and the service life of the water-permeable ceramic brick; the manganese ore residue acid additive in the ceramsite makes the stalactites react backward during long-term water shortage tobecome calcium oxide, and polypropylene fibers can improve the crack resistance and the toughness of the water-permeable ceramic brick, so the strength and the water permeability of the water-permeable ceramic brick are improved doubly, and the water-permeable ceramic brick has a broad application prospect.

Description

technical field [0001] The invention discloses a preparation method of a ceramic permeable brick, which belongs to the technical field of building materials. Background technique [0002] Permeable bricks have good water permeability and air permeability, which can quickly infiltrate rainwater into the ground, replenish soil water and groundwater, maintain soil moisture, and improve the living conditions of urban ground plants and soil microorganisms. Rainwater accumulation and flooding often occur in cities. The ground paved with permeable bricks can effectively relieve the flood discharge pressure of the urban drainage system due to its good water permeability. At the same time, permeable bricks have the functions of water seepage, moisturizing and ventilation. It is a new type of building material for urban construction. It is laid on urban roads and squares, which is conducive to improving the urban ecological environment and avoiding the "heat island" phenomenon. [00...
