초록

Sewage facilities mainly consisted of concrete structures are being deteriorated seriously by biodeterioration originated from sulfur-oxidizing bacteria. To prevent biochemical corrosion of the sewage concrete, antibiotics which prevent growth of sulfur-oxidizing bacteria were developed. Recently, to evaluate biochemical corrosion properties of concrete, antimicrobial performance and resistance to sulfuric acid were investigated respectively. But, in this study, to evaluate it complexly, concrete specimen covered with antibiotics were exposed in the actual sewage environment and were investigated about corrosion properties after three months. As a result, weight change ratio, nature potential and sulfuric ratio of concrete covered with antibiotics were less than plain concrete.
