セメント産業のCO2排出削減策としてクリンカ低減や代替バインダーが注目されるが、耐久性への影響が未解明。本レビューは過去10年の48論文を分析し、CO2削減量の定量化は多いものの、使用段階の耐久性評価が不足していることを指摘。細孔構造やアルカリ性の変化が耐久性に影響するが、長期的な統合研究が欠如している。
English
This systematic review of 48 studies on low-carbon cements finds that most research quantifies CO2 avoidance from clinker reduction but neglects durability and service life. Durability is mainly linked to pore structure and alkalinity, yet long-term integrative studies are lacking. The review highlights the need for holistic assessments of decarbonized cement performance.

📄 Abstract（原文）
The cement industry accounts for approximately 7% of global anthropogenic CO2 emissions, making clinker reduction, alternative binders, and carbon use and capture technologies essential mitigation strategies. However, decarbonization based on the replacement of clinkers with supplementary cementitious materials or alternative binders generally adjusts the materials’ physicochemical properties and reactivity. As these actions may have implications for durability and performance throughout the life cycle, this paper presents a systematic review, based on the Methodi Ordinatio approach, of studies published in the last decade in indexed databases that examine the relationship between low-emission cements, durability, and service life. Of 48 selected articles, most focused on quantifying CO2 avoidance through clinker reduction, without comprehensively addressing the use phase. When present in the literature, durability is found in studies of chloride penetration and carbonation resistance. However, no integrative chain studies or long-term studies focused on the durability of less emissive cement-based materials were identified. Across the reviewed studies, durability was mainly associated with changes in pore structure, hydration products, transport properties, and matrix alkalinity. Fine and reactive additions may promote pore refinement and restrict the ingress of aggressive agents, whereas extensive clinker replacement and portlandite consumption may reduce the alkaline reserve and increase carbonation susceptibility. However, these relationships are strongly dependent on binder composition, replacement level, and curing conditions, and were rarely evaluated together over sufficiently long periods.
