Foam concrete can be used as a protective layer for floor heating, but the appropriate density and thickness should be selected according to the specific situation.
1. Introduction of foam concrete
Foamed concrete is a kind of lightweight insulation material, composed of cement, sand, bubble foaming agent and other raw materials mixed. It has a very good thermal insulation performance, corrosion resistance, fire prevention, seismic, sound insulation, convenient construction and other characteristics. It is widely used in the construction field in the manufacturing of partition wall, floor plate and other components, and also used for some special occasions of heat insulation and filling.
2. Advantages and disadvantages of foam concrete as a protective layer of floor heating
1. Advantages
(1) good insulation effect: foam concrete has good heat insulation performance, can effectively reduce the heat dissipation.
(2) High compression strength: after strengthening the foam concrete treatment, its density can reach 250-600 kg/m³, this density of foam concrete can withstand the ground pedestrian activities and slight pressure of motor vehicles, can well protect the floor heating pipe.
(3) Simple construction: foam concrete can be directly poured on the ground, do not need to be like mud and sand concrete, pressure, pull wire and other complex construction process.
3. Application of foam concrete in floor heating protection layer
Because foam concrete has good thermal insulation performance and compression strength, foam concrete can also be used in the floor heating protective layer. But the following work needs to be done well:
(1) Choose the appropriate density and thickness: foam concrete as the floor heating protective layer needs to have a certain compression strength, it is generally recommended to use foam concrete with a density of 300-500 kg/m³ and a thickness of 5-8cm.
(2) before construction should be a good waterproof treatment: foam concrete as the floor heating protective layer, needs to have a certain waterproof effect, to ensure that the floor heating pipe will not be eroded by water.
(3) Add another layer of floor heating protective film to the foam concrete surface layer to improve the protection performance.
[Conclusion]
Foam concrete can be used as a protective layer of floor heating, but the appropriate density and thickness should be selected according to the specific situation. Before the construction, do more waterproof measures to ensure the safe operation of the floor heating pipeline.
