Abstract

The invention provides a porous concrete vegetation brick, a preparation method thereof and application. The product is excellent in breathability, has a certain nutritional ingredients and appropriate pH conditions and is filled with nutrient soil to plant plants. The plants completely cover a brick base frame, root systems of the plants go deep into the porous concrete brick base frame, and a decoration building material similar to a tile or cultured stone is formed. According to three-dimensional greening environmental characteristics, the prefabricated vegetation brick which can be applied to wall greening construction can be manufactured, and a convenient, quick and low-cost construction mode is provided for wall greening. In sum, the porous concrete vegetation brick is simple and practical, does not need to be fixed through a welding steel frame and is cheap in cost, economical, quick in greening effect and long in service life, the convenient, quick and low-cost construction mode can be provided for wall greening, and the porous concrete vegetation brick has an excellent popularization prospect.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a porous concrete vegetation brick, its preparation method and application. Background technique [0002] While concrete has made great contributions to my country's urbanization process, it has also created countless gray and monotonous buildings and impermeable ground, forming an urban landscape of "gray forest". Traditional concrete is neither permeable nor air permeable, which blocks the exchange of water and air on the surface, causing frequent urban waterlogging and strengthening of the heat island effect. Both at home and abroad are studying how to improve these urban problems in order to reduce environmental damage and energy waste. [0003] Wall greening is a measure for people to carry out vertical greening on building walls, walls, bridge columns, balconies, window sills, etc., so as to improve the urban ecological environment; It is a technology dev...
