本研究旨在探討自充填混凝土在不同之標準要求下，使用電弧爐碴取代粗粒料對於自充填混凝土特性的影響，以體現低成本、環保、廢棄物資源化及永續利用之精神。研究內容可分為三大部份：第一部份是針對電弧爐碴替代粗粒料對於自充填混凝土各新拌之填充性、流動性等性質影響加以探討，第二部份則是對於硬固混凝土在不同齡期下的抗壓強度、劈裂強度等力學性質之觀察，最後對於電弧爐碴自充填混凝土的長度變化量、電阻值及電滲值等耐久性質加以分析及討論。期能對自充填混凝土應用於業界有所助益。 This study investigate the feasibility of using electric arc furnace slag (EAFS) to replace part of natural coarse aggregates in self-compacting concrete and check the performances for these mixes. Due to the nature of EAFS, the self-compacting concrete made with it can achieve multiple goals such as low cost, environmental friendly, recovery from waste and sustainable use. Three parts are included in this study: (1) to investigate the self-compacting capability and flowability for self -compacting concretes made by various replacement percenatges of coarse aggregate by EAFS; (2) to study the mechanic properties, such as compressive strength and splitting tensile strength, for self-compacting concretes at different ages; (3) to study the length change, Wenner’s four probe resistivity and repid chloride penetration test (RCPT) values for self-compacting concretes.
