Abstract

The invention provides a manufacture method for highly antifreezing concrete permeable bricks which are prepared by using ceramic wastes as aggregates and a compound additive. According to the invention, ceramic wastes are recovered, crushed and screened; ceramic waste particles with a particle size of 1.25 mm to 5 mm are selected as aggregates for a permeable concrete surface layer; the selectedparticles are mixed with cement, pigments and the compound additive to form a surface layer material; the particle size of cobblestones at a bottom layer is 2.5 mm to 10 mm; the compound high performance concrete additive is composed of a high efficiency water reducer, an organosilicon waterproof agent and the mineral additive silica fume. The invention enables the problems of poor strength of permeable concrete and poor frost resistance in chilly areas to be overcome; the highly antifreezing concrete permeable brick prepared from ceramic waste aggregates has the characteristics of high strength, substantial permeable effects, good frost resistance, etc., is an environment-friendly construction material, and is especially applicable to ground laying of urban squares, commercial streets, sidewalks, community activity places, parking lots and the like in urban construction in chilly areas.

Description

technical field [0001] The patent of the present invention relates to a method for manufacturing high-freeze-resistant concrete permeable bricks made of waste ceramic aggregates, and specifically relates to a preparation process for producing high-quality concrete permeable bricks by using waste ceramics, reducing costs and improving the frost resistance of concrete permeable bricks. Background technique [0002] At present, the ground in urban construction such as city squares, commercial streets, sidewalks, community activity venues, and parking lots are mostly paved with impermeable materials such as cement pavement bricks, ceramic glazed bricks, granite, marble, and asphalt concrete. These grounds prevent the infiltration of rainwater and affect urban flood drainage. The hot season increases the urban heat island effect and affects the comfort of the urban environment. In 1979, near a church in the Sarasota area of ​​Florida, the United States, sand-free porous concrete ...
