Table 3: Moisture sensitivity of each parameter to concrete panels analysis. temperature of the panel, and this effect only had a fluctuation effect on the panel's humidity. It did not affect the moisture inside the concrete with the average humidity over a period of time. (2) Direct influence occurred through the internal moisture of the panel directly affected by changes in panel humidity. Factors such as ambient humidity, ambient temperature, maintenance methods, and wind speed could reduce or increase the panel's humidity and have a direct impact. Among these, the maintenance method and environmental humidity had a direct impact on the panel's moisture replenishment and loss, while environmental temperature and wind speed had an indirect impact on humidity by affecting the diffusion rate of moisture within the panel.
