摘要

在臺灣製造的太陽能板占了全球25%的產量，也使臺灣成為世界上第二大生產國，因此亦製造了大量的事業廢棄物。故在未來持續發展太陽能此環保能源的趨勢下，廢棄物勢必會逐年增加，目前臺灣每年生產多達1000噸的廢棄電池玻璃，針對廢棄太陽能板破碎後研磨成光電矽晶粉進行成分分析，其中SiO_2比例高達75%，且重金屬含量皆符合國內環保署規範，顯示光電矽晶粉有潛能應用於水泥基質複合材料作為膠結材、微細之填充材料或卜作嵐材料使用。基於「永續發展」的精神，將廢棄材料永續利用以及降低廢棄材料對於自然環境污染等因素，亦即所謂綠色混凝土之推展，更為本研究之首要目標。再者，考量綠色混凝土實用性，重要考量為阻止有害物質侵入面層破壞，塗封材料為優質方法，塗覆於表面產生阻絕效果，延長結構物使用年限；然而塗封材料種類眾多，但多數採有機質塗封，形成物理屏障薄膜於混凝土表面，有機塗封材料可能對環境或人體造成危害，隨時間累積，塗膜受環境因素老化或剝離，導致混凝土喪失保護功能。而若改用無機塗封材料，是否可避免上述缺點，達到永續保護能力仍值得探討，則為本研究之另項目標。利用EDS、XRF及TGA分析，可驗證塗封材料可滲入表面下約10mm並發生結晶反應。

Solar panels made in Taiwan accounted for 25% of global production, but also to make Taiwan become the world's second largest producer, thus also created a large number of industrial waste. Therefore, in the trend of the future sustainable development of this environmentally friendly solar energy, waste is bound to increase year by year, the current Taiwan produce up to 1,000 tons of solar glass waste annually. Considering grounded photovoltaic solar panel silicon powder, in which SiO2 ratio of up to 75%, and the heavy metal contents are in compliance with domestic EPA specification, have the potential to be used in the cement-based composite material as a binder material, the fine filler material or a pozzolanic materials. Based on the spirit of sustainable development, the sustainable use of waste materials and the less pollution to the natural environment, this study presents the so-called development of green concrete, namely the major goal of this research. Next, the practical use of green concrete in market needs to prevent various unlike materials into the cracks and porosities and to reduce the strength and durability. Use inorganic sealer material in order to prevent intrusion of hazardous material and repair concrete. Coating in the surface may reduce permeability and increase concrete durability. But there are too many types of coating and most of them are organic which will become physical barrier of concrete surface treatment. Such organic coating materials have the decisive shortcoming of being air-polluting during manufacturing process as well as during coating works. Surface coatings aging and peeling caused by environmental factors, which could cause concrete loss of protection and degradation again. Inorganic sealer material is adopted to compensate this disadvantage, and it becomes the other goal of this study. Depth of penetration capability by EDS, XRF and TGA shows sealer layer at 0 - 10mm under the concrete surface has been affected by the penetration of CSM.
