Analyzing and mapping the current status, hotspots, and perspectives of lightweight cellular concrete: A bibliometric evaluation from 2000 to 2022

Lightweight cellular concrete (LCC) is being widely utilized in engineering due to its advantageous properties such as light weight, adjustable strength, and self-supporting capabilities after the curing process. However, there is a lack of scientometric studies on LCC and insufficient attention has been given to the overall trends in this field. This paper aims to analyze the existing literature on LCC to identify the current research focal points and provide insights into future research directions. The research and review literature on LCC in the Web of Science Core Collection database from 2000 to 2022 were analyzed using scientometric methods in R language and VOSviewer software. The findings were visually presented to analyze the annual distribution of research, author contributions and collaborations, influential institutions and countries/regions, co-citation patterns, highly cited literature, keyword co-occurrence, and research frontiers. This analysis aimed to summarize the general characteristics of research in the field of LCC during the specified period. The field of LCC still encounters numerous challenges related to sustainability, strength enhancement, development of new materials, and expansion of applications. Nevertheless, it also presents promising opportunities for growth. With extensive research and innovation, LCC is anticipated to emerge as a significant material in the construction and engineering domain in the future.
