道路緣石添加色料與反光料試驗之研究
Experimental Study on Producing Road Curbs by Adding Pigments and Reflective Materials
摘要
本論文主要在於探討改善道路混凝土護欄反光與強化美觀效果之手法，採用氧化鐵顏料、回收玻璃粒料、夜光粉及亮光漆等灌製混凝土試體或表面塗層處理，利用數位相機拍攝各試體之影像，再經由影像分析軟體 ImageJ分析試體影像之色彩空間、試體耐候性及夜光放光反應等之影響。 本研究將氧化鐵顏料控制在 10%水泥用量，玻璃粒料取代細骨材用量控制在 30%以內，製作不同配比之彩色、玻璃及彩色玻璃混凝土試體，養護結束後進行一系列試驗，試驗結果顯示，氧化鐵顏料黃色及綠色對混凝土之坍度影響最大，玻璃粒料之添加可增加混凝土之流動性；在抗壓強度方面，添加紅色氧化鐵顏料之混凝土抗壓強度大於無任何添加之基礎混凝土，最低之抗壓強度為添加綠色氧化鐵顏料之混凝土；添加氧化鐵顏料或玻璃粒料之混凝土試體，對於表面之色彩空間及耐候性較基礎混凝土試體穩定；添加玻璃粒料取代細骨材並無法提高 RGB值及 V值（明度）；氧化鐵顏料紅色及黃色之添加，除增加色彩之 S值（飽和度），更增加了 V值（明度），提高混凝土試體對光之反射量，其次為黃綠色試體，最差為綠色試體。

This study aims to analyze how to improve the reflection and strength the beauty of road rails concrete. To meet the aims, this study undertakes ferric oxide pigment, recycled glasses sand, luminous powder and clear lacquer to produce the concrete and surface treatment. Using the digital camera to take every concrete specimens’ pictures, and the software- ImageJ to analyze the effects of concrete specimens’ color, exposed to different weather conditions, luminous reflective effects and fundamental properties. This research use the ferric oxide pigment that control in 10%, and glasses sand that under 30 % to replace the fine aggregates and make the different colors, glasses and colored glasses concrete specimens. From this study, we can know that the yellow and green ferric oxide pigment have the biggest effect on the concrete slump. Adding the glasses sand can increase the concrete fluidity. This research also found that add the red ferric oxide pigment to concrete can have the highest strength, and the green ferric oxide pigment can have the lowest strength. Adding the ferric oxide pigment and glasses sand to concrete can have stable weather conditions and color on the surface. Using the glasses sand to replace the fine aggregates couldn’t improve the RGB and Value. Adding the red and yellow ferric oxide pigment can improve the Saturation, Value and reflection. On the other hand, green ferric oxide pigment have the worst Saturation, Value and reflection.
