[0002] The combined wall (or combined structure wall) refers to a wall structure combined by different materials or components, which is usually used in buildings to provide structural strength, sound insulation, heat insulation and other functions. The tailing material concrete refers to a kind of green building material using mine tailings as aggregate to replace traditional aggregate (such as sand and stone) in concrete. The tailing material concrete not only meets the sustainable development concept of modern green building, but also effectively reduces the dependence of the construction industry on natural resources, reduces production cost, relieves environmental pressure, and has great application potential.
