Abstract: Water-permeable bricks are a new type of pavement bricks. The laying of permeable bricks can strengthen the exchange between the surface and groundwater and alleviate waterlogging disasters in the city. In recent years, there has been lots of related research on the pre-paration and using characteristics of permeable bricks. On the other hand, with the continuous development of industrialization, a large amount of industrial solid waste has been produced. If improperly disposed of, these wastes will not only occupy a large amount of valuable land resources, but also do harm to the local soil, atmosphere as well as water environment. On the other side, industrial solid waste contains a large amount of inorganic nonmetallic oxides such as SiO2 and Al2O3, which are common components in the preparation of bricks. Therefore, producing permeable bricks use industrial solid waste can not only reduce the harm to environment, but also can save the production cost of permeable bricks, which can bring benefits both environmentally and economicly. There have been a large number of studies on the use of industrial solid waste to prepare environmental friendly permeable bricks. However, due to the wide variety of industrial solid wastes and their different characteristics, related studies are relatively scattered. It is urgent to summarize the reaction principles of these studies for further research. Based on relative papers domestic and foreigners, this article summarizes the aspects of raw material characteristics, production process, reaction mechanism and characterization methods for preparing permeable bricks from industrial solid waste. The pore structure of permeable bricks is an important factor affecting the strength and water permeability of permeable bricks. Research on the pore structure of permeable bricks can provide a basis for the production of permeable bricks. Therefore, this article focuses on the distribution type, formation mechanism, and characterization methods of the pore structure of permeable bricks, and numerical simulation methods to study the permeability of permeable bricks based on the study of pore structure. Finally, based on the current research of environmental friendly permeable bricks made from industrial solid waste and their pore structure, the research focus and prospects of this field are summarized.
