本論文は、ラムドアース等の土系建設材料を、持続可能性・工学・耐久性・実務適用の観点からレビューしたものである。土系材料は、embodied energy、輸送需要、炭素排出、建設廃棄物を削減し、高い室内快適性や熱容量、リサイクル性を提供する。一方、引張強度の低さ、湿気による劣化、ひび割れ、土質のばらつきが普及の制約となっている。マレーシア・日本・中国の事例から、材料選定、締固め工法、構造ディテールの改善が性能向上に有効と示される。
English
This review examines earth-based construction materials, especially rammed earth, from sustainability, engineering, durability, and practical application perspectives. Earth materials can cut embodied energy, transport demand, carbon emissions, and construction waste while offering indoor comfort, thermal mass, and recyclability. Barriers include low tensile strength, moisture deterioration, cracking, and variable soil properties. Cases from Malaysia, Japan, and China show that material selection, modern compaction, and structural detailing improve performance.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
建設業の脱炭素はScope 3上流（建材調達）やライフサイクル評価と直結する。日本では住宅・建築物の省エネ基準適合義務化や非住宅建築物のZEB化が進む中、低炭素建材の選択肢として土系材料の位置づけを整理する意義がある。SSBJや有報でのScope 3開示を意識した建材調達戦略にも示唆を与える。
In the global GX context
Embodied carbon in construction is increasingly material to Scope 3 upstream accounting and ISSB/CSRD disclosure. This review contributes to global scholarship on low-carbon building materials by synthesizing standards and durability evidence, though it remains a qualitative review rather than a quantitative LCA study.

📄 Abstract（原文）
Earth has been used as a construction material for thousands of years and is now receiving renewed attention as a building material with minimal environmental effects. This study explores the development of earth-based construction, with particular attention to rammed earth, from sustainability, engineering, durability, and practical application perspectives. Earth construction techniques, including rammed earth, cob construction, compressed earth blocks, adobe, and wattle and daub, are discussed together with their social, environmental, technical, and economic benefits. In addition, this study reviews international standards and guidelines related to material properties, soil selection, durability, structural design, energy performance, and indoor environmental quality. The results show that earth-based materials can reduce embodied energy, transportation demand, carbon emissions, and construction waste while offering high indoor comfort, long service life, sufficient thermal mass, and recyclability. Although earth-based construction has several advantages, its wide application is still limited because of low tensile capacity, construction limitations, moisture-related deterioration, cracking, and varying soil properties. Furthermore, projects from Malaysia, Japan, and China prove that careful material selection, modern compaction methods, and proper structural detailing can substantially increase the performance of rammed earth. The overall performance of rammed earth mainly relies on consistent design standards, durable low-carbon stabilization methods, and improved structural and seismic performance.
