本研究は、廃レンガ粉末（WBP）、廃セラミック粉末（WCP）、大理石粉末（MP）をセメント代替材として組み合わせた37種類のモルタル配合を評価。三成分系では10%MP+20%WBPが90日圧縮強度約65MPaを達成し、10%MP+10%WCPがEEI、ECI、MCIを約25%削減しつつ良好な力学性能を維持。最適な三成分系リサイクル結合材が低環境負荷モルタルの可能性を示す。
English
This study evaluates 37 mortar mixtures combining waste brick powder (WBP), waste ceramic powder (WCP), and marble powder (MP) as cement substitutes. Ternary mix 10%MP+20%WBP achieved highest 90-day compressive strength (~65 MPa), while 10%MP+10%WCP reduced embodied energy, carbon, and cost by ~25% with satisfactory mechanical performance. Optimized ternary recycled binders show potential for lower-impact cement mortars.

📄 Abstract（原文）
Although waste brick powder (WBP), waste ceramic powder (WCP), and marble powder (MP) have been individually investigated as cement substitutes, their combined effects on rheological behaviour, mechanical performance, and strength-normalised environmental efficiency remain insufficiently understood. This study evaluates 37 mortar mixtures, including 12 ternary formulations with cement replacement levels ranging from 5% to 40%. Fresh-state properties were characterised through water demand, setting time, slump, yield stress, and plastic viscosity, whereas compressive strength was determined at 3, 7, 28, and 90 days. Strength-normalised embodied energy (EEI), embodied carbon (ECI), and material cost (MCI) were also assessed. WBP increased water demand and rheological resistance, whereas MP improved flowability through particle-packing and dilution effects. WCP exhibited intermediate rheological behaviour while maintaining satisfactory workability at moderate replacement levels. Binary mortars containing up to 25% WBP or WCP maintained compressive strength close to the control at 28 days. Among the ternary mixtures, 10% MP + 20% WBP achieved the highest 90-day compressive strength (≈65 MPa), whereas 10% MP + 10% WCP provided the best overall sustainability-performance balance, reducing EEI, ECI, and MCI by approximately 25% while maintaining satisfactory mechanical performance. These findings demonstrate the potential of optimised ternary recycled binders for producing lower-impact cement mortars.
