Abstract

To reduce carbon emissions in cement production and maintain productivity with an abundantly available supplementary cementitious material, research into limestone calcined clay cement (LC³) has been gaining prominence. This study aims to understand the research gaps, emerging themes, and innovation perspectives by examining the data and metrics of published articles found in the SCOPUS database, using the VOSviewer, Bibliometrix and Pajek software tools. This bibliometric analysis, while focused on LC³, intentionally includes studies on calcined clays due to their importance as a key component and the relevance of technological advancements in this area for LC³ development. Keyword analysis highlighted a predominant focus on reactivity and mechanical performance, while revealing underexplored areas such as durability, sustainability and rheology. Emerging themes include LC³ performance in harsh environments, circular economy applications, and post-fire scenarios. The findings point to future research directions emphasizing clay rheology and comprehensive life cycle assessments, contributing to the advancement of LC³ as a sustainable cement alternative.

绘制煅烧粘土和LC3的研究景观：新兴挑战和机遇的文献计量学视角

为了减少水泥生产中的碳排放，并通过大量可用的补充胶凝材料保持生产力，对石灰石煅烧粘土水泥（LC3）的研究日益受到重视。本研究旨在通过使用VOSviewer、Bibliometrix和Pajek软件工具，检查SCOPUS数据库中已发表文章的数据和指标，了解研究差距、新兴主题和创新视角。这一文献计量学分析虽然侧重于LC3，但由于煅烧粘土作为关键组成部分的重要性以及该领域的技术进步与LC3发展的相关性，因此有意包括了对煅烧粘土的研究。关键词分析强调了主要关注反应性和机械性能，同时揭示了未开发的领域，如耐久性、可持续性和流变性。新兴主题包括恶劣环境下的LC3性能、循环经济应用和火灾后场景。研究结果指出了未来的研究方向，强调粘土流变学和全面的生命周期评估，有助于LC3作为可持续水泥替代品的发展。
