项目标书摘要：泥渣类废弃物烧制环保水泥之水化反应机制研究(I-Ⅲ)根据行政院环保署估计,2010 年时台湾地区石化产业每年约产生22 万公吨左右的废泥渣(包括石土粉及废触媒),五十万公吨以上之石材污泥对环境之污染亦为民众及相关单位所重视。在另一方面，台湾地区每年必须消耗大量砂石及水泥等消乏性营建无机资材，此等资材与原料之供需不均与过度开发，造成天然资源循环极度失衡及环境负荷。前述废弃物之资源化成为营建资材，正可以舒缓失衡之程度，减轻环境污染负荷，并於营建资材之天然原料与无机废弃物间，建立起一「物质流循环与平衡」,而为极具意义之重要环境课题。泥渣类废弃物(包括石土粉、废触媒、石材污泥及煤灰矿泥，以下简称泥渣类废弃物)之主要成份为Si、Al、Ca 其在烧制处理过程可形成铝酸钙、矽酸钙之化合物，包括CA、C12A7、C3A、C3S 及CA2 等晶相，系属一般波特兰水泥中之重要成份，将来资源化後取代部份水泥，因而在废弃物处理及资源化方面，极具潜力。然而泥渣类废弃物烧制环保水泥之水硬性性质及整体水化反应行为尚未明了，且实际应用於环保水泥之水化反应特性及工程应用上也需进一步加以厘清了解。本研究计画拟提三年之延续性计划，兹说明如下:◎第一年：环保水泥之操作条件与环保水泥品质特性研究 ◎第二年：环保水泥之物化特性及水化反应机制 ◎第三年：环保水泥浆体之水化反应动力学预计本计划完成後可提升国人对泥渣类废弃物资源化再利用之技术，并有助於石化等产业之泥渣类废弃物处理及100%全资源化回收再利用，以达到零排放及循环型社会构筑之目标。

Application Abstract: Hydration Mechanisms of Eco-cement by Co-sintering Treatment fromWaste Sludge and Ash(I-Ⅲ)According to the ROC EPA statistics(Environmental Protection Administration),by the year 2010,there will be more than 220,000 tons per year of residues(including limestone sludge,and spent catalysts)discharged from petroleum refining industry islandwide.In addition,there will be more than 500,000 tons of stone sludge generated in Taiwan.Their treatment/disposal and environmental impact has become a major public concern.On the other hand,the annual consumption of depletive natural resources,such as aggregates and raw materials for producing cement,is also substantial.The uneven distribution between supply and demand,as well as excessive mining and depletion has resulted in an extremely unbalanced recycling of natural resources.The recovery and recycling of the aforementioned inorganic residues for construction materials can mitigate the extent of the imbalance and provide the possibility of creating a more balanced flow via the recycling of material,alheviating between the depletion of natural resources and the excessive generation wastes that require disposal.The major components in waste sludge and ash(including limestone sludge,spent catalysts,stone sludge and iron oxide sludge,herein referred to as waste sludge and ash)included silica,aluminum,and calcium.Consequently the waste sludge and ash will through the sintering process,produce such compounds as calcium aluminates and calcium silicates,which include CA,C12A7,C3A,C3S,CA2,etc.Such compounds,which are also common in ordinary Portland cement,can function as binders,and exhibit self-hardening characteristics.There have been very few publications concerned with the effects of the composition on the hydration activity of waste sludge and ash co-sintered for reuse as eco-cement,therefore,the present work is aimed at alleviating this lack of information.This study will investigate the utilization of waste sludge and ash co-sintered as eco-cement.The research is divided into three sections as follows.● Study on the Co-sintering Conditions of Waste Sludge and Ash and Eco-cement Quality Characterization(1st year)● Study on the Hydration Reactions for Eco-cement Pastes(2nd year)● Hydration kinetics of Eco-cement Pastes(3rd year)It is hoped that the results of this study will contribute to the promotion of waste sludge and ash recycling technologies,to help attain the goal of sustainable development helping to establish a recycling society with zero discharge.
