セメント製造は世界のCO2排出の約8%を占め、道路建設が主要な消費者である。本研究は、2014〜2024年の62件の論文を系統的にレビューし、フライアッシュ（20-40%）、GGBS（30-50%）、籾殻灰（10-15%）の最適置換率で強度が維持・向上し、RCPT値が40-60%低下することを確認。CO2排出を10-45%、 embodied energyを8-35%削減する。設計優先度に基づくSCM選択マトリクスと4つの研究ギャップを提示。

Cement production accounts for ~8% of global CO2 emissions, with road construction a major consumer. This systematic review of 62 papers (2014-2024) finds optimal SCM substitution ratios (fly ash 20-40%, GGBS 30-50%, RHA 10-15%) maintain or improve strength, reduce RCPT by 40-60%, and cut CO2 by 10-45% and embodied energy by 8-35%. Provides an SCM selection matrix and identifies four research gaps.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本の建設業界では、コンクリートの脱炭素化が急務であり、国土交通省のグリーンインフラ施策やカーボンニュートラルポートの取り組みと関連。SCMの最適配合は、日本のセメント産業のCO2削減目標や、公共工事での低炭素材料調達に示唆を与える。
In the global GX context
This review supports global efforts to decarbonize construction, aligning with ISSB/CSRD disclosure requirements for embodied carbon. The SCM selection matrix offers practical guidance for infrastructure projects seeking to reduce Scope 3 emissions, relevant for TCFD-aligned reporting and green procurement policies.
👥 読者別の含意

📄 Abstract（原文）
With its contribution reaching approximately 8% of total anthropogenic CO₂ emissions globally, the cement manufacturing sector stands as one of the most carbon-intensive industries in existence — and road construction, as its primary consumer, shares a substantial portion of that environmental burden. This study aims to systematically synthesize empirical findings from previous research on green concrete in rigid pavement applications, focusing on material performance and environmental impact. Following a systematic literature review protocol, 62 articles selected from Scopus, Web of Science, and ScienceDirect databases (2014–2024) were comprehensively analyzed; of this full corpus, 21 references with the most representative and significant findings are cited in the bibliography as the primary citation base for this article. Synthesis results confirm that the three primary SCMs — fly ash (optimal ratio: 20–40%), GGBS (30–50%), and rice husk ash/RHA (10–15%) — maintain or enhance compressive and flexural strength at optimal substitution levels, with RCPT values 40–60% lower than conventional concrete. Hybrid SCM combinations demonstrate superior synergistic performance. From an environmental perspective, SCM substitution consistently reduces CO₂ emissions by 10–45% and embodied energy by 8–35%. The study also produces an evidence-based SCM selection matrix by design priority and implementation context, and identifies four critical research gaps.
