本研究は、石灰石焼成粘土セメント（LC3）の様々な配合を熱力学モデリングとLCAで評価。クリンカーを65%から35%に低減する配合で、カーボアルミネート相の形成による緻密な微細構造が確認された。LC3-50配合が水和生成物の安定性と材料効率の最適バランスを示し、LCAでは地球温暖化係数が32.92%削減されるなど環境負荷低減が実証された。
English
This study applies thermodynamic modeling and life cycle assessment to limestone calcined clay cement (LC3) formulations with clinker content from 65% to 35%. The formation of carboaluminate phases yields a denser microstructure. The LC3-50 mixture achieves an optimal balance between hydration stability and material efficiency, with LCA showing a 32.92% reduction in global warming potential and a 40.78% reduction in ozone depletion potential, supporting LC3 as a sustainable building material.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では2050年カーボンニュートラル目標達成のため建設分野の脱炭素が急務。LC3は既存設備で製造可能な低炭素セメントであり、日本のセメント産業における排出削減策として有望。本論文は配合最適化に科学的根拠を提供し、実用化促進に寄与する。
In the global GX context
Globally, cement production accounts for ~8% of CO2 emissions. LC3 offers a scalable low-carbon alternative by substituting clinker with widely available calcined clay and limestone. This work provides rigorous thermodynamic and LCA evidence for optimal formulations, supporting its adoption in decarbonizing the construction sector.

📄 Abstract（原文）
To meet the net-zero CO2 goal by 2050, low-carbon construction materials like limestone calcined clay cement (LC3), which replaces a large portion of clinker with calcined clay and limestone, are essential. This study used thermodynamic modeling and life cycle assessment to evaluate a range of LC3 formulations with clinker content from 65% to 35%. Results show aluminate-CaCO3 interaction forms stable carboaluminate phases, leading to a denser microstructure. While lower clinker content leads to a decrease in pH and solid volume, the LC3-50 mixture achieved the optimal balance between hydration product stability and material efficiency. LCA confirms that reduced clinker content significantly lowers environmental impacts across all indicators, most notably achieving a 32.92% reduction in global warming potential and a 40.78% reduction in ozone depletion potential. These findings offer a scientific basis for optimizing LC3 mixtures and promoting its use as a sustainable building material.
