日本語
本研究では、リサイクル骨材と低炭素セメント（LC³、ジオポリマー）を用いてM30グレードの環境配慮型プレキャストコンクリートを開発した。最大50%の天然骨材をリサイクル材で置き換えても強度・耐久性は通常のコンクリートと同等であり、製造時のエンボディドカーボンを削減できる。サーキュラーエコノミーを促進する実用的な建設材料の提案である。
English
This study develops eco-friendly precast concrete (M30 grade) using recycled aggregates and low-carbon binders such as LC³ (limestone calcined clay cement) and geopolymer. Replacing up to 50% of natural aggregates with recycled materials maintains strength and durability while reducing embodied carbon. It offers a practical path toward circular economy in construction.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建設業界はCO2排出の主要源であり、国土交通省もグリーン建材の活用を推進している。本研究成果は、再生骨材と低炭素セメントの組み合わせによるエンボディドカーボン削減方法を示しており、日本のGX実装やサーキュラーエコノミー政策に直接貢献し得る。
In the global GX context
Globally, embodied carbon in construction is a growing focus for net-zero targets and green building certifications (e.g., LEED, BREEAM). This paper provides a replicable method for reducing concrete's carbon footprint using widely available recycled materials and novel low-carbon cements, supporting transition finance and ISSB-aligned disclosure of Scope 3 emissions in construction supply chains.
👥 読者別の含意
🔬研究者:Provides empirical data on strength and durability of low-carbon concrete with recycled aggregates, informing further material optimization and LCA studies.
🏢実務担当者:Construction companies can adopt these mixes to reduce embodied carbon and meet green building requirements, potentially lowering material costs.
🏛政策担当者:Supports policy incentives for recycled aggregates and low-carbon cement in building codes and public procurement.
📄 Abstract（原文）
<title>Abstract</title> <p>The construction industry is one of the main causes of global warming. However, a new type of “green” concrete could help reduce this problem and support a net-zero future. This study created eco-friendly precast concrete of M30 grade by replacing traditional materials with recycled waste and low-carbon options like LC³ (limestone calcined clay cement) and geopolymer binders. The results are good for the environment. By replacing up to 50% of natural stone with recycled materials, the concrete still has the same strength and durability as normal concrete. This method also reduces “embodied carbon,” which means the pollution created during manufacturing. At the same time, it helps save natural resources. The study shows that sustainable materials can be used in modern construction. It offers a practical way to support a circular economy, where waste is reused instead of thrown away. In simple words, this research suggests that future cities can be built using recycled materials without harming the Earth.</p>
