Research evolution of limestone calcined clay cement (LC3), a promising low-carbon binder - A comprehensive overview.

ABSTRACT

Limestone calcined clay cement (LC3) is a recently developed binder with huge potential to reduce the clinker factor in cement and the environmental impact. This study aimed to evaluate the evolution of the research on LC3 by conducting a bibliometric analysis, evaluating key metrics such as publications, authorships, sources, or countries, to provide greater knowledge and a strategic vision of this technology. This work provides an important perspective of the field and elucidates the research trends and path that the LC3 technology followed from its beginning to date. The analysis reveals a noticeable increase in technology readiness and researchers' interest, as indicated by a significant rise in publications' number over time. Also, the authorship metrics reveal an important cooperation between communities in the development of this technology. The research on LC3 is essential since the technology is a viable and reliable approach to decreasing the cement industry's carbon footprint.
