Abstract

The invention belongs to the technical field of building materials and particularly relates to an environment-friendly water-permeable brick for sponge city and a preparation method of the environment-friendly water-permeable brick for sponge city. The water-permeable brick is in a structure of two layers connected together vertically and comprises an upper layer namely a face layer and a lower layer namely a bottom layer. The face layer is prepared from cement, silicon sand, additives, pigments and water. The bottom layer is prepared from coarse aggregates, cement, additives, water and a water reducing agent. The water-permeable brick prepared according to the method is excellent in compressive strength, breaking strength, porosity, permeability coefficient and the like and capable of meeting requirements of roads.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an environment-friendly permeable brick for a sponge city and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and the acceleration of urban modernization, a series of urban problems have emerged, such as noise, air pollution, heat island effect, lack of groundwater resources, etc. The construction of ecological cities has attracted more attention. Sidewalks and non-motorized lanes are an important part of urban roads and one of the important links in the construction of ecological cities. Permeable roads will directly reflect the livability of cities and the ratio of urban landscapes to greenery. [0003] At present, the roads in cities are all built in the past. At that time, people did not have the kind of advanced environmental protection awareness, so people almost all use impermeable road s...
