建設業の高排出・資源消費に対応するため、可視光で空気中汚染物質を分解する光触媒材料グラファイト状窒化炭素（g-C3N4）をセメントモルタルに添加する研究。さらに廃ガラス由来のガラス粉末を混和材として用い、廃棄物削減と耐久性・機械的特性の向上を両立させる。ハイブリッド材料の機械的・環境的特性を評価し、低光量の都市環境での持続可能な建築材料としての可能性を示す。
English
This study integrates graphitic carbon nitride (g-C3N4), a visible-light photocatalyst, into cement mortar to break down airborne pollutants and enable self-cleaning surfaces. Waste-derived glass powder is added as a supplementary cementitious material, improving durability and mechanical performance while reducing waste. Mechanical and environmental properties of the hybrid mortar are assessed to gauge its viability for sustainable building applications in low-light urban settings.

📝 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（カテゴリ1・3）や建材由来排出の削減が焦点となる。本論文は廃ガラス活用と大気浄化という素材レベルでの環境付加価値を示すが、SSBJ・有報での開示や炭素会計への直接的な示唆は限定的。建材メーカーやゼネコンの環境訴求材料として参考になる。
In the global GX context
Construction materials sit at the heart of Scope 3 category 1 and 3 emissions, and low-carbon or functional building products are increasingly relevant to CSRD/ISSB disclosure narratives. This paper offers a materials-science angle—photocatalytic air purification plus waste-glass valorization—rather than a disclosure or accounting contribution, so its global GX value is mainly as an example of embodied-carbon and circularity innovation in cementitious products.
👥 読者別の含意
🔬研究者:Materials researchers can note the dual-function approach (pollutant degradation + waste glass valorization) as a template for sustainable cement composites.
🏢実務担当者:Construction and building-materials teams may consider photocatalytic, waste-glass mortars for urban facades where air-quality and circularity claims add value.
🏛政策担当者:Regulators could view photocatalytic building materials as a complementary urban air-quality and circular-economy lever, though standards and verification remain open.
📄 Abstract（原文）
: Since the construction industry has high emission rates and resource demanding rate, whose effect on the environment is tremendous in a destructive sense, there is need of sustainable building materials. One of the potential options to reduce air pollution and promote self-cleaning materials is adding photocatalytic component to cementitious ones. The photocatalytic capabilities, affordability, and durability of graphitic carbon nitride (g-C 3 N 4 ) under visible light makes the breakdown of airborne contaminants possible, as it is a polymeric semiconductor that has gained attention towards its use as building materials. Moreover, in addition to the sustainability of the material, the use of glass powder as an additional cementitious component created through recovered waste glass enhances the durability and the mechanical properties of the material by reducing waste. Photocatalytic mortar is manufactured out of glass powder and g-C3N4 and it fits in low-light urban conditions as it removes pollutants and enhances the performance of materials. The study ascertains the potential of the materials through examination of the mechanical and environmental properties of the hybrid materials to be applied in sustainable building applications
