本研究は、産業副産物（フライアッシュと高炉スラグ）を活用したセメントフリーのアルカリ活性化複合材料を開発。アルミノケイ酸塩材料ベースのカプセル（AMC）を10%添加することで、圧縮強度の回復率が112–118%に向上し、塩化物イオン浸透抵抗性が79.4%改善され、ASTM C 1202の「非常に低い」透水性基準を達成した。この成果は、建設業界のCO2排出削減と産業副産物のリサイクルに貢献する。
English
This study developed cement-free alkali-activated composites using industrial byproducts (fly ash and blast furnace slag). Adding 10% aluminosilicate material-based capsules (AMCs) improved compressive strength recovery to 112–118% and enhanced chloride-ion penetration resistance by 79.4%, meeting ASTM C 1202's 'very low' permeability criteria. These findings support CO2 emission reduction and industrial byproduct recycling in construction.

📄 Abstract（原文）
The construction sector is currently tasked with the critical challenge of minimizing CO2 emissions associated with cement manufacturing. To support a sustainable building environment, this research developed cement-free alkali-activated composites by leveraging industrial by-products, specifically fly ash and blast furnace slag. The study experimentally evaluated how aluminosilicate material-based capsules (AMCs) composed of a mixture of fly ash, blast furnace slag, and ferronickel slag powder affect the composites’ durability, mechanical properties, and self-healing capabilities, alongside microstructural investigations. Results indicated that specimens incorporating 10% AMC reached a compressive-strength recovery range of 112–118%, which represents an improvement of approximately 10% compared to the control sample. Furthermore, the 28-day resistance to chloride ion penetration was enhanced by 79.4%, successfully meeting the ‘very low’ permeability criteria defined by ASTM C 1202. These results suggest that cement-free self-healing composites incorporating AMCs are a viable alternative for reducing carbon emissions and minimizing environmental impact in the construction industry. Furthermore, the recycling of industrial byproducts, as demonstrated herein, contributes to sustainable development in response to climate change.
