1. An accelerated corrosion test method wherein corrosion of a reinforcing steel contained in a reinforced concrete specimen having a crack with an inside that extends to the reinforcing steel so as to expose a surface of the reinforcing steel is accelerated, wherein
a control terminal is connected both to a moisture sensor contained within the reinforced concrete specimen, and to a weight measuring instrument that measures a weight of the reinforced concrete specimen, and controls a moisture supply and removal device, thereby alternately and repeatedly performing:
a wetting step of supplying a moisture to the inside of the crack in the reinforced concrete specimen so that the moisture extends to the exposed surface of the reinforcing steel; and
a drying step of terminating the wetting step and removing the moisture in the inside of the crack and the moisture on the exposed surface of the reinforcing steel when the moisture is detected in the moisture sensor, or when change in slope of weight change of the reinforced concrete specimen is detected, after the start of the wetting step.
