The Applications of Foam Concrete (Part Two)

1. Pipeline Backfill
As for the endless trouble of abandoned oil tank, pipeline, underground sewage pipe and other holes easy to cause fire or landslides can be cope with by the foamed concrete backfill and the cost is relatively is lower. The density of foam concrete used depends on the diameter of the pipe and the water level. Generally it is 600-1100 kg/m³

2. Lean Concrete Fill Layer
Due to the use of flexible hoses, foam concrete has a great deal of work and adaptability, so it is often used for lean concrete fill layer. If the request on heat insulation is not high, we usually adopt the lean concrete fill layer with the density of 1200 kg/m³ and average thickness of 0.05 m. If the request on heat insulation is not high, we will use the lean concrete fill layer with the density of 500 kg/m³ and average thickness of 0.1-0.2m.

3. Slope Roof
Foam concrete used in roof slope, has many futures in light weight, quick construction speed and low cost. Foam concrete needed is generally slope of 10 mm/m, thickness of 0.03-0.2 m, density of 800-1200 kg/m³.

4. The Bottom Tank Support
The foam concrete pouring at the bottom of the storage tank also can form a convex foundation if necessary. This ensures that the whole of the bottom support optimum stress during welding. The continuous support can make the tank with the bottom plate. At the same time convex foundation is also easy to clean. The suitable density of foam concrete machine is 800-100kg/m³.

5. Others
Foam concrete can also be used for the insulation of the firewall populated, soundproofing floor filling, tunnel and liner backfill; and the power supply, water piping of isolation, etc.
