单独使用环氧树脂或缓蚀剂对钢筋混凝土结构中钢筋的防护效果有限。为取得更好的防护效果，本文尝试将缓蚀剂和环氧树脂组合使用，采用半电池电位法测定缓蚀剂和环氧树脂不同涂刷顺序对混凝土构件中钢筋的防护效果。试验结果表明，先涂一层缓蚀剂再覆盖一层环氧树脂对混凝土构件中的钢筋防护效果最佳，能有效降低钢筋的腐蚀电位，使构件中钢筋的腐蚀概率小于5%，因此，缓蚀剂与环氧树脂的组合使用能有效保护钢筋不被腐蚀。
單獨使用環氧樹脂或緩蝕劑對鋼觔混凝土結構中鋼觔的防護效果有限。為取得更好的防護效果，本文嘗試將緩蝕劑和環氧樹脂組閤使用，採用半電池電位法測定緩蝕劑和環氧樹脂不同塗刷順序對混凝土構件中鋼觔的防護效果。試驗結果錶明，先塗一層緩蝕劑再覆蓋一層環氧樹脂對混凝土構件中的鋼觔防護效果最佳，能有效降低鋼觔的腐蝕電位，使構件中鋼觔的腐蝕概率小于5%，因此，緩蝕劑與環氧樹脂的組閤使用能有效保護鋼觔不被腐蝕。

The protection cannot show the intact effectiveness when epoxy resin or corrosion inhibitors is used alone on the reinforced steel concrete structure. In this paper, making a combination of epoxy resin and corrosion inhibitors is tried for getting a better protective effect, and half-cell potential method is used to determine the protective effect of epoxy and corrosion for reinforced concrete structure when they are applied in different order. The results show that brushing a layer of corrosion inhibitor then covering a layer of epoxy corrosion inhibitor has a better protection on reinforced steel concrete structure, which can effectively reduce the potential corrosion of the steel and makes the probability of corrosion of steel members less than 5%. Therefore, using the combination of corrosion inhibitor and epoxy resin can effectively pro-tect steel from corrosion.
