文摘

Temperature and humidity inside the concrete were measured. The surface temperature of the concrete was observed as higher by 6 °C during summers and lower by 2 °C during the winters. The inner temperature of the concrete was affected by temperature, solar radiation and radiation cooling. The temperature and humidity changes can be predicted by developing a FE coupling numerical analysis model. The temperature and humidity information of the concrete would contribute in the prediction of concrete’s deterioration.
