Recently, the problems such as the stability, service life estimation, the maintenance, and rehabilitation of reinforced concrete structures become more important, and will be emphasized more crucially in the near future. It is also necessary to develop a proper diagnostic evaluation procedure which allows us to better evaluate the deterioration of concrete structure, to inspect the reinforced concrete structure, to determine whether the reinforced structure needs to be demolished or not, and finally to choose proper rehabilitation strategy. In this research, the monitoring system based on previous researches is systematically evaluated. The fundamental research objective is determined based on the evaluation, and actual experiments are performed. Ultimately, the self monitoring apparatus (SMA) system which allows monitoring the service life of the reinforced concrete structure is suggested. The suggested monitoring system (SMA) consists of 1st spacer indicating perceivable material, 2nd spacer indicating protection material, and 3rd spacer indicating cover depth of reinforcing steel. These elements are placed in the reinforced concrete structure as a unified system. |
