橡膠煉製所需之補強劑及填充劑（白煙），其製程所產生的廢白土（white carbon sludge）污泥，含有團聚狀之二氧化矽（SiO2）奈米粒子，於廢棄過程可能會有對生態環境造成污染之疑慮。但因該廢白土為卜作嵐材料，是否可資源再用於混凝土？殊值研究探討。本文研究試驗先將廢白土進行X光繞射（XRD）分析與掃瞄式電子顯微鏡／能量頻譜（SEM/EDS）之觀測分析，其後分別選取二種水膠比0.485與0.55，以0、2.5、5、10及15%水泥體積取代率之方式，灌鑄成5×5×5-cm^3之廢白土水泥砂漿試體（SBCM）與純水泥砂漿試體（OPCM），進行抗壓強度試驗與質量成長之量測等，並探討其卜作嵐反應之特性。試驗結果顯示，該廢白土可取代部分水泥於砂漿中使用，除可減少水泥之生產與CO2排放，亦可符合節能減碳與永續發展之需求。

The purpose of this study is to explore the possibility of using white carbon sludge (WCS), a by-product from the manufacturing rubber of chemical industry, to replace partial cement in cement-paste, cement-mortar and cement-concrete. The emphases are on its material strength and engineering properties. WCS sludge is rich in hazardous nano-particles of SiO2 and other debris of unknown organics. These hazardous ingredients may harmful to the ecological environment, and the WCS sludge may be a pozzlanic material suitable recycling in cement concrete, which worth to investigate.WCS sludge were firstly conducted for XRD analysis and SEM/EDS analysis, the test result demonstrate that their are pozzolanic material, then we adopted the water/cementitious ratio of 0.485 and 0.55, and used 2.5, 5.0, 10.0, and 15.0 % cement replacement to mold the WCS sludge-blended cement mortar (SBCM; experiment group) specimen and ordinary Portland cement mortar (OPCM; control group) specimen are also to be made for comparisons, which are compressive strength test, and mass growth measurement. Those experiment tests will be conducted to evaluate the feasibility of reuse WCS sludge in practical engineering. The goal of this study is to transform the waste materials of WCS sludge into a useful resource to eliminate its disposal problems and appeal to the sustainable development of earth.
