Thermal Properties Of Concrete

[JoeH78]

DEar All,

Does anyone knows what is the thermal conductivity coefficient of normal, light weight and fine aggregated concrete material? I've seen that it is taken as 2,5W/(m*K) in some calculations in from technical books but I'm unsure about that.

Eurocode 1992-1-2:2004 suggests it varies from about 1.4 - 2 at 0C to about .6 at 1200C
