| 摘要(中) | 本研究利用營建用鋼筋為基材，以無電鍍方式將鋼筋表層析鍍一層鎳磷合金鍍膜之無電鍍鎳鋼筋，置於一般混凝與添加不同比例海砂之混凝土試體，施以加速凍融循環環境測試，以了解其對混凝土性質之變化情形及無電鍍鎳磷合金鍍膜對於鋼筋防蝕之效果。 試驗結果顯示，雖然無電鍍鎳鋼筋與一般鋼筋於腐蝕電位量測方面雖無明顯差異，但由試體拉拔後鋼筋之外觀檢視可發現，一般鋼筋於第100循環時，三種試體即陸續產生程度不等之銹斑，而無電鍍鎳鋼筋直到600循環結束僅於B試體（海砂）及C試體（河砂＋海砂）出現微量銹斑，可見無電鍍鎳鋼筋於凍融環境下之防蝕成效良好。在握裹強度試驗方面，無電鍍鎳鋼筋與一般鋼筋並無明顯差異，顯示無電鍍鎳鋼筋之鍍膜性質對鋼筋之握裹強度並無影響。 | |||
| 摘要(英) | The research is
conducted based on tests on steel, which is an essential construction
material, coated with nickel phosphorous alloy using electroless-plate
method. Reinforced concrete samples with the coated steel using 3
types of fine aggregates (river sand, beach sand, and river/beach sand)
were prepared and tested under simulated aggravating freeze/thaw cycling
circumstances to explore the effects of the coating on physical/chemical
properties of the concrete and corrosion potential of the reinforcement
steel. The results of the tests revealed that there is a little difference in electrode potential, which is an indication of corrosion potential, between the coated and uncoated steels. However, results indicated that coated steels exhibit much fewer rusty spots throughout the surface of the steel, and the rust stated to develop at more freeze-thaw cycles than the uncoated steels. This implies that electroless nickel plated steel may have less corrosion potential under freeze/thaw cycling conditions. Moreover, results also revealed that there is no apparent change in bonding strength between the concrete and reinforcement when the coated steels were used. | |||
