Due to the presence of numerous sealed tiny pores in foamed concrete, it boasts excellent thermal properties, specifically superior thermal insulation capabilities, which are not found in conventional concrete. Foamed concrete, typically with a density range of 300-1200 kg/m3, has a thermal conductivity of 0.08-0.3 W/(m·K) and a thermal resistance about 10-20 times that of ordinary concrete. Using foamed concrete as building wall and roof materials offers excellent energy-saving effects. Insulating lightweight aggregate concrete, structural insulating lightweight aggregate concrete, and structural lightweight aggregate concrete, made widely using陶粒 (táolì, a type of ceramic granule), are extensively applied in both industrial and residential buildings.The United States primarily utilizes it in high-rise buildings for lightweight structural concrete and load-bearing components. Its applications are also widespread, such as in Texas, where thousands of kilometers of highways are paved with asphalt ceramic aggregate concrete, which boasts strong anti-skid properties and reduces the accident rate. In some European countries, ceramic aggregate concrete is extensively used in construction projects as wall materials, and also as roof insulation and thermal insulation materials. Sweden and Finland extensively employ ceramic aggregate concrete in road and dam construction, as well as in the construction of bridges in areas with poor durability. Shanxi Province in China has adopted pumice concrete.150mThey have revolutionized the chimney lining process by utilizing a new "double-slide" construction technique, which allows the outer shell and lining to be built simultaneously, thereby overcoming the outdated and inefficient manual bricklaying process. This innovation addresses the challenges of constructing tall chimneys.
