To solve the problems of high energy consumption and high pollution of buildings,China has been ac‐tively promoting the development of green,energy-saving and environmentally friendly wall structures.Among them,as a new type of wall structure,the lattice concrete shear wall structure has multiple functions such as heat preservation,energy saving,sound insulation,fire resistance,light weight bearing,convenient construction and environmental protection,becoming a hot spot of application and research in recent years.This study briefly in‐troduces the form of lattice concrete wall structure,summarizes the axial compression,corrosion resistance,ther‐mal,sound insulation,weather resistance,seismic and other properties of lattice concrete wall,and puts forward the problems and deficiencies in the research of lattice concrete wall at present.It shows that the development of lattice concrete wall structure is a major demand for the recycling of building materials and construction waste,which can be used for seismic design of building structures.In the future,its physical properties can be improved from the aspects of new materials,overall structural fire prevention,freeze-thaw in complex environment,etc.,and the research on recoverable functionality and high-rise application can be carried out in combination with shock absorption technology to further improve its seismic performance.It provides important scientific basis and technical support for the wide application of lattice concrete walls and their structures.
