Özet
In this study, both experimental and theoretical investigations are performed to obtain new concrete types with high thermal insulating characteristics for energy-efficient buildings. In this regard, 102 new concrete wall samples were produced using different aggregates at different volume fractions, and their thermophysical properties were tested according to EN and ASTM standards. The experimental research focused on developing new wall or roof types with higher thermal insulation properties in order to reduce the energy consumption of buildings due to heating or cooling. In order to specify the thermal performance of developed lightweight concretes, an analytical solution method is developed by the Complex Finite Fourier Transform CFFT method to estimate heat gain utilizing measured thermophysical properties data of those samples. The results indicated that the reduction in heat gain value was obtained as 83.21 % for the PC100 wall corresponding to conventional concrete. Consequently, the thermal insulation effect of those samples shows excellent potential for development.
