因應2050淨零碳排的國家政策，營建業者積極開發降低混凝土碳排之技術。針對預拌混凝土業者於生產及澆灌作業後常見之剩餘料（流動態混凝土下腳料），本研究添加高吸水性樹脂，經乾燥與過篩後成為預拌回收再生細粒料（Recycled Ready-Mix Aggregate , RRA），並依配比需求重新拌合混凝土、製作鋼筋混凝土梁、柱構件，進行反覆載重實驗並探討其耐震性能。實驗計畫包括實驗組之2座柱試體，實驗變數為軸壓比（10%、30%），及2座梁試體，實驗變數為跨深比（2.0、4.0）。對照組則是採用文獻中一般卜作嵐水泥混凝土梁、柱，實驗組與對照組之間除材料性質外，其餘設計參數均相同。實驗結果顯示，預拌回收再生細粒料混凝土與一般卜作嵐水泥混凝土相比，抗壓強度、遲滯迴圈、最大側力、位移韌性、初始勁度皆相近。此外，依照FEMA 356、ACI 374.1-05性能評估結果，驗證預拌回收再生細粒料混凝土所澆灌之梁柱構件，具有與一般卜作嵐水泥混凝土構件相近且可用的耐震性能。此外本研究也有使用TEASPA+ETABS和SERCB+ETABS進行實驗結果模擬，驗證既有兩種的耐震評估工具對於預拌回收再生細粒料混凝土梁、柱構件皆有良好比對效果，有助於在工程實務應用與節能減碳。

In response to the national 2050 Net-Zero Emissions policy, the construction industry is actively developing technologies to reduce concrete's carbon footprint. This study focuses on residual concrete commonly generated during production and pouring operations. Superabsorbent polymers (SAP) were added to the residual material, which was then dried and sieved to produce Recycled Ready-Mix Aggregate (RRA). This RRA was used to produce recycled concrete for the fabrication of reinforced concrete (RC) beam and column components. The seismic performance of these components was evaluated through cyclic loading tests. The experimental program consisted of two column specimens with varying axial load ratios (10% and 30%) and two beam specimens with varying shear span-to-depth ratios (2.0 and 4.0). Control groups using conventional Portland cement concrete (PCC) were established in accordance with the existing literature, maintaining identical design parameters except for material properties. Experimental results indicate that RRA concrete exhibits compressive strength, hysteretic loops, maximum lateral force, displacement ductility, and initial stiffness comparable to those of conventional PCC. Furthermore, performance evaluations conducted in accordance with FEMA 356 and ACI 374.1-05 confirmed that RRA concrete components exhibit seismic performance levels comparable to those of PCC components, thereby confirming their structural viability. Additionally, this study employed TEASPA+ETABS and SERCB+ETABS to simulate experimental results. The simulations validated that both seismic assessment tools provide accurate predictions for RRA concrete components, facilitating the practical application of this material in engineering and contributing to energy conservation and carbon reduction.
