Abstract

In order to prevent blistering of waterproofing membranes due to evaporation of moisture from the concrete, this paper describes a solution where a permeable sheet was provided between the concrete and the waterproofing membrane. However, if the humidity of the external environment is higher than for the concrete, moisture may enter the concrete. It is important to understand the moisture content of concrete when considering the durability of reinforced concrete. In this study, the moisture content of the concrete and the environmental humidity were used as parameters, and the effect of the construction method of the waterproofing membrane on the moisture content of the concrete and the corrosion rate of reinforcing steel bar were examined.
