Abstract

The invention relates to a water permeable brick prepared from basalt tailings. The water permeable brick comprises a surface layer and a bottom layer, wherein the surface layer is prepared from raw materials in parts by weight as follows: 85-95 parts of basalt tailing powder with particle size being 20-40 meshes, 2-8 parts of molecular sieve waste and 2-8 parts of clay; the bottom layer is prepared from raw materials in parts by weight as follows: 70-80 parts of basalt tailing powder with particle size being 5-20 meshes, 10-20 parts of the basalt tailing powder with particle size being 20-40meshes, 2-8 parts of the molecular sieve waste and 2-8 parts of the clay. According to the water permeable brick prepared from the basalt tailings, solid waste including the basalt tailings and the molecular sieve waste is taken as the raw materials, resource recycling of the solid waste is realized, and location resources occupied by landfill are reduced; the water permeable brick obtained by sintering has excellent properties, and the properties are better than indicators specified by national standards.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of basalt tailings, and in particular relates to a permeable brick prepared by using basalt tailings. Background technique [0002] With the continuous acceleration of urbanization, the continuous expansion of urban construction areas, the degree of hardening of roads has increased year by year, the intensity of urban development has become more and more intense, the effects of "heat island" and "rain island" have increased year by year, and the original flood storage and stagnation areas have been crowded out. , because the construction of drainage facilities lags behind the development of urban construction, a series of urban water safety issues arise. For example, the impermeable ground in the urban area makes it impossible for rainwater to infiltrate. In addition, the original urban underground drainage pipes are aging and the drainage system is not perfect. Flood path, the low-lying ...
