Mapping the Innovation–Implementation Gap in Sustainable Construction Materials: Global Trends, Knowledge Structures, and Translational Priorities
Brent Begay
Discipline: Material Science
Abstract:
Background: The construction industry is a major contributor to global carbon
emissions and resource depletion. Although sustainable construction materials
(SCMs) support climate mitigation and circular development, implementationrelated research remains less explored despite advances in material innovation
and laboratory validation.
Methods: This study employed a bibliometric analysis of SCM research indexed
in Lens.org from 2010 to 2025. Bibliometric mapping and performance analyses
were conducted using Biblioshiny/Bibliometrix (R package) and VOSviewer to
examine publication trends, collaboration networks, citation structures, and
thematic evolution.
Results: A total of 9,601 eligible records were analyzed. SCM research expanded
rapidly, with a 23.95% annual growth rate, an average document age of 4.94
years, and 22.38 citations per document. Research outputs were led by China,
the United States, Australia, India, and the United Kingdom. Influential journals
and studies focused on geopolymers, alkali-activated materials, recycled
aggregates, fly ash, durability, and low-carbon cement alternatives. Keyword
co-occurrence and thematic analyses highlighted compressive strength,
microstructure, durability, geopolymers, and circular economy, while regulation,
standardization, scalability, and industry adoption remained underexplored.
Conclusion: SCM research has expanded rapidly but remains dominated by
studies of material performance and sustainability. Implementation-related
themes remain underrepresented, indicating an imbalance between material
innovation and practical deployment in the construction sector.
