Foreign lightweight boards were developed mainly after 70 years, including glass fiber reinforced cement (GRC) boards, asbestos cement boards, cement foam boards, calcium silicate boards, and various insulation materials (rock wool, mineral wool, polystyrene foam, rigid polyurethane, etc.) composite panels, metal surface composite panels, steel wire mesh polystyrene. Ethylene sandwich panels and so on. Due to the scarcity of resources and limited land, Japan attaches great importance to the development of all kinds of light-weight board, among which the research and production of autoclaved calcium silicate board and glass fiber reinforced cement products (GRC) occupy a leading position in the world. The ECO-panel developed by a German company is a kind of lightweight hollow wallboard, which can be used as load-bearing or non-load-bearing wallboard with cement, gypsum or lime as raw materials, mixed with a certain amount of fiber and additives, and mixed with up to 50% fly ash.
"Green building materials" is the development direction of all countries in the world today. The concept of "green building materials" was first put forward by the 1st International Research Institute on Materials Science and Technology in 1988. The concept of "green building materials" refers to the degree of contribution to the environment expressed by green degree, and points out the possibility and feasibility of sustainable development. "Green" has become a symbol of human desire for environmental protection. In 1992, the international academia clearly put forward the definition of green materials: "green building materials" refers to materials which have the smallest load on the earth's environment and are beneficial to human health in the process of using raw materials, manufacturing, using or recycling, and waste disposal. According to the definition of "green building materials", green wall materials should be a new type of wall materials which do not destroy land, save energy, save water, benefit waste and reduce environmental pollution. In short, lightweight, high strength, high efficiency, green environmental protection, and new composite wall materials are the current and future development trend.
