セメント系建材に熱電機能を付与し、建物廃熱回収と構造セルフセンシングを両立させる研究のレビュー。ポルトランドセメント系とアルカリ活性材料（AAM）の2系統について、イオン・正孔・電子の電荷輸送機構、炭素系フィラーや半導体粒子・産業固形廃棄物による改質戦略、細孔溶液・細孔構造・温湿度・養生条件がゼーベック係数等に与える影響を整理する。AAMは高いイオン濃度に由来する熱電能を持つ一方、イオン-電子混合伝導や水分分配による出力不安定化が課題であり、フィラー凝集やスケールアップ等の実装ボトルネックと今後の研究方向を示す。
English
Reviews thermoelectric cementitious materials that combine building waste-heat recovery with structural self-sensing. It compares Portland-cement and alkali-activated systems, covering ionic/hole/electron transport, modification via carbon fillers, semiconductors and industrial solid waste, and how pore solution, pore structure, humidity and curing affect Seebeck coefficient and conductivity. AAMs show strong intrinsic thermoelectric power but suffer mixed ionic-electronic conduction and moisture-driven instability; filler agglomeration and scalable p-n device fabrication remain barriers.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
省エネ建築・ZEB推進や建設業の脱炭素技術として、建材自体の機能化という視点を日本のGX実務に提供する。ただしSSBJ開示や投資家対応への直接的示唆は乏しく、技術シーズとしての位置づけにとどまる。
In the global GX context
Adds to the global building-decarbonization and energy-efficiency literature by framing structural materials as energy-harvesting assets, relevant to green building standards and Scope 1/2 building emissions reduction, though it does not engage disclosure frameworks directly.

📄 Abstract（原文）
Thermoelectric cementitious materials, capable of integrated building waste heat recovery and structural self-sensing, serve as core functional materials for intelligent low-carbon buildings. Existing research mainly focuses on two material systems, Portland cement-based and alkali-activated materials (AAMs). Based on fundamental thermoelectric theories, it reviews the transport mechanisms of three types of charge carriers, namely ions, holes, and electrons, sorts out modification strategies incorporating carbon-based fillers, semiconductor particles, and industrial solid wastes, and elaborates the coupling effects of pore solution, pore structure, temperature–humidity conditions, and curing regimes on the Seebeck coefficient, electrical conductivity, and thermoelectric figure of merit. The intrinsic thermoelectric performance of plain cement matrices is inferior, and performance enhancement relies on the construction of solid-state percolation networks via conductive fillers. By contrast, AAMs feature high ion concentrations in pore solutions and exhibit prominent intrinsic thermoelectric power; nevertheless, mixed ionic-electronic conduction readily forms within such systems, and the output stability is drastically disturbed by water allocation. Large-scale engineering applications are hindered by several bottlenecks, including filler agglomeration, strong environmental susceptibility, and challenges in scalable fabrication of p–n thermoelectric devices. This paper proposes future research perspectives: developing low-cost modification routes using solid wastes and biomass, fabricating self-healing stable material systems, establishing quantitative coupled ionic-electronic transport models, and advancing the practical deployment of thermoelectric components in waste heat harvesting and structural health monitoring. This work provides theoretical references for performance optimisation and industrial translation of thermoelectric cementitious materials.
