According to Uysal [19], for a specific concrete mixture, when the amount of cement increases by 25%, the density increases and therefore conductivity increases by 3%. thermal properties of concretes. Moreover, thermal conductivity of concretes are used in ground source heat pump applications [6], [7]. Up to now, although there have been many studies related to thermal properties of concrete, there was no study that investigate the thermal conductivity of concrete or reinforced concrete according to bar The thermal conductivity values of concrete the palm fibre from arenga pinnata Merr addiction are 0.47 W/mºC, 0.52, W/mºC, and 0.44 W/mºC for specific gravity values 1.0 with 0.5 %, 2.0 %, and 2 %. The conductivity of concrete depends on the type of aggregate, moisture content, density, and temperature of concrete. When concrete is saturated, the conductivity ranges generally between 1.4 and 3.4 j/m2sc/m.

|% & ! & % # "" " ! '% % | One of these simplifications is that the thermal conductivity of the concrete matrix is described by one sin gle temperature-dependent limit function. EN 1992-1-2 contains two temperature-dependent limit func-tions for the thermal conductivity of concrete. The purpose of this analysis of lightweight concrete, i.e., wood-concrete and EPS-concrete, at various moisture contents. These results qualitatively confir m the theoretical predictions presented in the first part of the paper.

Several methods for calculating concrete thermal conductivity have been Thermal conductivity is the flow of energy through materials. Most of us are aware that a wood-framed wall is essentially 30 percent or more un-insulated due to the amount of solid stud area displacing the fiberglass batts. The same concept exists for insulation systems in concrete panels.
