Concrete screed thermal conductivity
Concrete has a very low coefficient of thermal expansion. However, if no provision is made for expansion, very large forces can be created, causing cracks in parts of the structure not capable of withstanding the force or the repeated cycles of expansion and contraction. The coefficient of thermal expansion of Portland cement concrete is 0.000009 to 0.000012 (per degree Celsius) (8 to 12 microstrains/°C)(8-12 1/MK). WebFields of application: Foam concrete is insulating, it can be used advantageously for leveling, e.g. as a base for floor screed. Foam concrete is suitable for thermal insulation between joists and underfloor heating, stable floating material and as fire insulation between ventilation pipes and the like.
