Nanotechnology in Construction Materials: Developments in Cement-Based Systems

為了解決Concrete cement的問題，作者Cerro-Prada, Elena 這樣論述：

Calcium silicate hydrate, as the principal component of the hydration of Portland cement, has been the topic of intensive research over the past several years. An understanding of the nature of this hydration product at the nanoscale is essential for the strategic modification of conventional cement

-based systems and the development of new materials with enhanced properties. This book will explore this topic and how to enhance concrete functionalities utilizing nanotechnology. Dr. Elena Cerro-Prada received her PhD in Physics from the Autonoma University of Madrid. She lectured at the Unive

rsity of Birmingham, UK, and worked at CERN within the Nobel Laureate Carlo Rubia, among other research and academic positions. Dr Cerro-Prada currently serves as Professor and Head of the Physics Department at the Technical University of Madrid. Dr. Cerro-Prada has contributed greatly to the unders

tanding of cementitious materials microstructure by applications of nanotechnology and nanomaterials. She is currently involved in the development of cement-based materials with photocatalytic properties as long as agent-based cementitious material modeling.

透水鋪面表面溫度降溫成效及預測模型

為了解決Concrete cement的問題，作者林佑亭 這樣論述：

隨著都市化（Urbanization）的速度加快，大量的開發導致不透水面積大大增加，大量工業氣體排放造成溫室氣體增加，且密集的建築物採用不透水且吸熱表面積大的材料，對環境生態產生負面的影響，迫使都市地區有水患之問題，環境溫度也大大提升，導致都市熱島效應加劇。而近年來，低衝擊開發（Low Impact Development, LID）已被證明為有效減緩都市熱島效應的方法之一。本研究目的以實際監測數據探討鋪面表面溫度對都市熱島效應之影響，並運用隨機森林（Random Forest, RF）演算法預測鋪面表面溫度。將以忠孝東路及新生南路交叉路口作為研究基地，於三種不同鋪面裝設溫度監測計，分別為透

水鋪面、瀝青鋪面以及不透水鋪面。透過實際量測蒐集大量數據，得知透水鋪面全年平均溫度可與瀝青鋪面相差約4°C，與不透水鋪面相差3°C；於降雨時雖氣溫會溼度增加而下降造成鋪面溫度隨之下降，但監測結果顯示鋪面溫度下降幅度大於氣溫降溫幅度，可得證水分增加會使鋪面表面溫度降低；在長時間無降雨情況下，降溫效果雖較不明顯，但透水鋪面仍為最低溫之鋪面並低於瀝青及不透水鋪面0.5-2°C。最後期望運用建置之機器學習模型進行不同情境下之模擬，並可將模型有效運用在其他地方。

應用新型助熔劑在常壓微波電漿反應器中穩定飛灰之研究

為了解決Concrete cement的問題，作者馬世隆 這樣論述：

目前焚化爐產生的飛灰由於其有毒化合物和重金屬含量高，不僅在環境方面會引起許多問題，而且在經濟方面亦會造成負面影響，因其需要大量資源來進行處理和最終處置。 本研究旨在微波電漿反應器中應用貝殼粉作為助熔劑來穩定飛灰，研究中有兩個實驗階段：第一階段著重於使用兩種氣體（氬氣和氮氣）處理飛灰以製備三種組合，第二階段基於使用三種不同比例之助熔劑，以田口法設計 (L9) 來計算功率、流量和時間等參數最佳數值。 研究結果顯示組合 3（飛灰 +貝殼粉 + 石英 + 氧化鋁 + 玻璃）的毒性降解效果最佳，此組合之重金屬去除量分別為：As (89%)、Hg (100%)、Cd(88%) 、Cr (79%) 、C

u (79%)、Pb (88%) 和 Se (97%)，而分析其礦物成分主要為矽灰石、鈣黃長石、富鋁紅柱石和方解石，並發現以氮氣作為載體氣體時可得最佳性能。而在第二階段試驗結果顯示樣品3，在以下參數數值操作下：功率-1,000w、流量-12L/M、時間-9分鐘、比例-4:2:1:1:2，可獲得相似的礦物組成，獲得富含二氧化矽、氧化鋁和碳酸鈣之材料。在氣體殘留結果方面，氬氣在降解VOC方面表現出良好的效果：25.4ppm（對照組）和24.4ppm（用助燃劑處理後）。本研究結果指出可以使用貝殼粉搭配一般助燃劑來有效穩定飛灰，並可獲得一種可應用於建築的回收新材料。
