Micro-environment temperature response prediction for fly ash concrete in artificial climate environment
Abstract：Heat conduction theory was used to predict the temperature response of fly ash con- crete. Measured thermal conductivity values were obtained in artificial climate environment. The thermal conductivity of the concrete drops as the amount of fly ash in the concrete in- creased. Thermal conductivity also increased as the relative humidity of the environment rose. These are linear relationships. Higher fly ash content reduces the sensitivity of the thermal conductivity value to environmental humidity. Response rate to thermal changes is higher at higher relative humidity. The thermal response of the samples is a non-steady state heat conduction problem and our theoretical analysis agreed well with the experimentally observed results.
