中文摘要 | 本文以蛇紋岩為對象,透過人工乾濕循環環境弱軟化岩石,模擬自然風化環境下岩石的崩解與分解過程,並透過相關室內試驗探討力學特性及吸附二氧化碳能力間的變化關係。研究結果獲知:在本文180個乾濕循環過程中,隨循環次數增加,蛇紋岩力學特性及抗風化能力略呈週期性變化,亦可能出現短週期增強現象,而吸附二氧化碳能力略有上升趨勢。迴歸分析結果顯示,力學特性及吸附二氧化碳能力間具高度相關性。研判係循環過程二氧化碳作用引起礦物相轉變,導致蛇紋岩一般指數及微觀組構出現變化,間接改變岩石力學特性所致。 |
英文摘要 | This study aimed to investigate the variation of mechanical properties and carbon dioxide fixation of serpentinite under man-made dried-wetted-cycling process. Experimental results showed that during 180 cycling processes, weathering resistance and mechanical properties have limited periodic increasing trend. The carbon dioxide fixation of serpentinite has also limited increasing trend. According to regression analysis, mechanical characteristics and carbon dioxide fixation are highly correlative. The carbon dioxide caused mineral phase change affecting physical indices, microstructure of serpentinite, and mechanical properties. |
