既有混凝土污水管線修復防蝕系統相關性能研究

Research on Related Functions of the Restoration of Anti-Corrosion System of Concrete Sewage Tubes

本研究主要探討，既有工業區污水管線修復防蝕系統之相關性能。針對本研究探討內容，設計二種配比模式之基材（1.使用Type II水泥以ACI配比所設計之混凝土；2.使用Type I水泥以緻密配比法所設計之高性能混凝土），試體製作完畢，於拆模後即進行水養護。並於養護28天齡期後，選定三家修補材料廠商（B廠、Y廠及L廠），其中包含樹脂類、及水泥材質之修補材料，進行修復防蝕系統之包覆工作。再利用各種試驗方法量測其相關性質（表面平整度觀測、表面電阻係數量測、氯離子電滲性質量測、加溫老化拉拔檢測），作為評定其修復防蝕性能之指標。經試驗結果及整體性評估後，二家廠商修補材料之修復防蝕性能為B廠＞Y廠＞L廠。且發現無論修補材料為樹脂類，或水泥材質，其修補後之整體性能仍與基材本身性質有密切關連性。

This research inquires the related functions of anti-corrosion system of the sewage tube in the industrial area. According to the research, two kinds of proportion modes are designed. (1. The concrete made by the Type II cement which was designed by ACI mixture proportion. 2. The high performance concrete made by Type I cement and designed by Densified mixture designed algorithm.). After concrete specimens were being curing in a period of 28 days, 3 restoration materials which were produced by different factories (B, Y, L) were selected to proceed the covering of the restoration of anti-corrosion system. Properties, such as surface leveling, surface resistivity and Chloride penetration, were examined as indicators of evaluating the ability of the restoration of anticorrosion functions. Results show that the sequence of the ability of the anti-corrosion function of these restoration materials are B > Y > L. And it is found no matter what kinds of restoration materials are used, properties of restored concrete sewage tubes are relatively related to the substance of the basic materials.
