Abstract

The invention relates to a method for preparing an environment-friendly water permeable brick, which uses riverbed deposited silt, construction sand and industrial waste glass as raw materials, adopts reasonable formulation and proper particle-grade composition pores to bake the environment-friendly water permeable brick at high temperature. The water permeable brick has water permeable function, water retention function, ventilation performance and multifunction property, can effectively inhibit the phenomenon of 'urban heat island', solves the natural waste material, namely Wei river sludge, treats the riverway, and achieves the aim of environmental protection.

Description

technical field [0001] The invention belongs to the field of utilization of solid waste and new building materials, and in particular relates to a preparation method of an environment-friendly permeable brick. Background technique [0002] At present, the phenomenon that the urban nighttime temperature is higher than the suburban nighttime temperature is called the "urban heat island phenomenon" or "urban high temperature phenomenon". This phenomenon is mainly caused by the use of non-permeable materials such as cement, asphalt, and marble to lay the ground in urban construction. These hardened pavements make it difficult to exchange heat and moisture between the ground surface and the air, and naturally adjust the temperature and humidity of the urban ground. Significantly lower, it is difficult for the surface to absorb heat, resulting in a large amount of waste heat in the urban space, and the ground will also reflect and radiate solar heat energy, greatly increasing the ...
