Building materials are various materials used in construction engineering. There are various types of building materials、 roughly divided into: (1) inorganic materials、 which include metal materials (including black metal materials and non-ferrous metal materials) and non-metallic materials (such as natural stone、 burnt earth products、 cement、 concrete、 and silicate products、 etc.). (2) Organic materials include plant-based materials、 synthetic polymer materials (including plastics、 coatings、 adhesives)、 and asphalt materials. (3) Composite materials、 including asphalt concrete、 polymer concrete、 etc.、 are generally composed of inorganic non-metallic materials and organic materials. The scientific and authoritative definition of ecological building materials is still in the research and determination stage. The concept of ecological building materials comes from ecological environmental materials. The definition of ecological environmental materials is still being studied and determined. Its main feature is firstly to save resources and energy; Secondly、 reducing environmental pollution and avoiding global warming and the destruction of the ozone layer; As an important branch of ecological environmental materials、 ecological building materials should refer to building materials that are designed and produced in harmony with the ecological environment during the production、 use、 disposal、 and regeneration cycle of materials、 meeting the requirements of minimum resource and energy consumption、 minimum or no environmental pollution、 optimal performance、 and maximum recycling rate. Obviously、 such environmental coordination is a relative and developmental concept P>
