Normally, the lightweight foamed concrete is used for insulation layer and levelling layer in radiant floor heating. By changing the ratio of ingredients such as an admixture, the fundamental properties of the lightweight foamed concrete could be changed. Due to the conductivity of this material, the characteristics of thermal output could be changed. So this study was aimed to evaluate the thermal output in radiant floor heating due to the mixture of materials in an aerated concrete. Firstly, the current foreign standards regarding the thermal output of radiant floor heating were reviewed. Nextly, the conductivity of lightweight foamed concrete was measured when the admixture and stabilizing agent were added for performance improvements. Finally, thermal output and downward heat loss were evaluated by changing the design parameter such as pipe spacing and water temperature differences. As the results, we could conclude that the conductivity of lightweight foamed concrete could be lowered by 0.12W/mK compared to the KS F 4039. Also the downward heat loss could be lowered by 20%. |
