Abstract

The invention discloses a sintered water permeable brick and a preparation method thereof, and belongs to the technical field of sintered ceramics. According to the water permeable brick, structural pug in a surface layer is composed of, by weight, 45-65% of structural fine aggregates, 20-30% of plastic high-temperature binders and 15-25% of water, pore forming pug in the surface layer is composed of, by weight, 20-50% of pore forming agent aggregates, 45-80% of plastic pore adding binders and 0-5% of biomass fuel internal combustion catalysts, and a blank of a secondary surface layer is composed of, by weight, 70-75% of coarse structural aggregates, 10-15% of plastic high-temperature binders, 0-5% of pore adding agent coarse aggregates and 10-15% of water. A blank of the surface layer and the blank of the secondary surface layer are prepared firstly, the blank of the surface layer contains the orderly distributed structural pug and the pore forming pug, and then single-shaft extrusion forming, drying and sintering are conducted to obtain the water permeable brick. The water permeable brick has high water permeable rate, high strength, high abrasion resistance and durability and is a paving material with excellent ecological and environmental functions.

Description

Technical field: [0001] The invention belongs to the technical field of sintered ceramics, and in particular relates to a sintered permeable brick and a preparation method thereof. The sintered permeable brick is especially suitable for the pavement of drainage systems in public places such as squares, roadsides, and stadiums that need to quickly leak rainwater, and is suitable for use in Permeable support layer for constructed wetlands. Background technique: [0002] At present, when building stations, squares, sports fields, roads and other public places, the problem of rapid drainage of rainwater must be considered. Therefore, drainage systems, such as drainage ditches, are designed under the square and on both sides of the road. Concrete bricks with drains are generally laid on these gutter faces, or floor drains are built at intervals of a long distance on the dense concrete brick pavement for draining accumulated water. Due to the usual roads and squares will accumula...
