An Experimental Study on the Fundamental Properties of. Sewage Concrete Covered with Inorganic and Complex Antibiotics

Recently sewage facilities mainly consisted of concrete structures are being deteriorated seriously by biodeterioration originated from sulfur-oxidizing bacteria. In this study, to prevent biochemical corrosion of the sewer concrete, antibiotics which prevent growth of sulfur-oxidizing bacteria were developed and antimicrobial performance of it was investigated. After that, to consider applicability of antibiotics to concrete, physical properties such as bond strength, resistance to abraision, water absorption and air permeability of concrete covered with inorganic and complex antibiotics were investigated.
