摘要

快速氯離子滲透試驗（RCPT），常用於混凝土耐久性的評估，但當添加飛灰取代水泥拌入混凝土時，由於飛灰顆粒較水泥小，因此會改變原有的孔隙細結構，同時也會消耗內部的氫氧根離子，導致在RCPT試驗過程中，總電量會大幅的下降，本研究的目的是利用對照組與飛灰組在綜合試驗結果的差異，設計出調整電量的方法。

The RCPT (Rapid chloride permeability test) usually used to estimate the concrete's durability. If we use fly ash to replace cement mix with concrete, the total electricity will drop significantly in RCPT. The reason result in this situation is the fly ash's granular structure is smaller than cement, it will change the structure in concrete and consume the Hydroxide ions in concrete simultaneously. In this study, we want to use the difference between fly ash group's and control group's Comprehensive test results to design the way of adjusting electricity.
