The United States, Britain, the Netherlands, Canada, Europe and the United States, as well as Japan, South Korea and other Asian countries, take full advantage of the good characteristics of foam concrete, it will be in construction engineering has been expanding and speeding up the progress of the project to improve the quality of the projects. In recent years, more and more attention to energy-saving construction work, with the energy-saving construction and the implementation of the policy, the popular energy-saving materials. Foam concrete in their good characteristics in the application of Chinas rapid development and application of the annual growth rate of about 8%, to become new large-scale thermal insulation material. Application summarized as follows:
I> building energy-saving insulation that this is the application of foam concrete is currently the most important purposes. Because of the existence of the internal closure of a large number of pores, pore and there are a lot of air exists, the air is very poor thermal conductivity properties, and its thermal conductivity is about 0.02 w / mk, it has greatly reduced its thermal conductivity properties, due to the non-stomatal Connectivity was closed and can not form a convection air circulation, at the same time concrete within the pores were isolated, and the ball for the pores serositis surrounded by concrete curing, the interface to increase capacity through the formation of large thermal resistance so that it will have excellent insulation性能.
1) roof insulation: foam cast-in-place concrete roof, energy-saving roof structure, including the general structure of the layer of insulation layer, layer to find slope, leveling layer and waterproof layer. Concrete used in roofing insulation foam insulation used on-site construction is the pouring of the method, the insulating layer, the layer to find slope, leveling a three-laminated, insulating layer simplify the process of construction, roofing and concrete to form a whole. Foam can also be made of concrete roofing insulation boards, bricks;
2) thermal insulation on the ground: cast-in-place to warm insulation, thermal insulation panels on the ground
3) wall insulation: cast-in-place, spray foam insulation layer of concrete walls, concrete block foam
4) composite wall panels: the frame structure used as insulation in the wall or filled with thin steel wall panels made of composite.
B> works
1) on the ground floor and returned to the ground:
2) The foundation: compensation for the foundation, roads, bridges, tunnels, large-scale structure of the filling layer.
3) retaining wall: the main road for protection, road, river banks, ports. Used as the main port of the coastal wall.
C> garden area
1) The use made of lightweight foam concrete rockery, bonsai
2) light water floating products, such as the floating landscape, plants, artificial hills, and so on
3) foam color decorative ceramic garden orphans, Fangmu materials
Four> Industry:
1) pipe insulation: pipe insulation
2) The application of fire-resistant: This is the concrete application of foam more successful in the field. The main furnace for cast-in-place insulation, spray insulation, fire-resistant insulation tiles, and so on.
3) chemical applications: storage tank at the end of the foot support, the bubble will be pouring concrete in steel tanks (containing crude oil, chemicals) at the end of the bottom of the foot and, if necessary, can also form the foundation of a convex, This is to ensure that the entire bottom of the support When the welding stress in the best condition for this support will enable the use of tank bottom plate. At the same time, the foundation is also easy to clean convex.
4) ceramic industry: Light foam ceramic products
