Why this paper matters
A landmark scientometric and bibliometric review in Frontiers in Materials surveying over 1,200 international publications on Engineered Geopolymer Composites (EGC), mapping global research clusters across micromechanical PSH design, precursor chemistry, fiber-matrix interfaces, 3D additive construction, and lifecycle decarbonization.
Main contribution
- Performs a comprehensive scientometric and bibliographic analysis of Engineered Geopolymer Composites (EGC) using VOSviewer network mapping across Scopus and Web of Science databases.
- Identifies the five principal research clusters defining modern EGC: (1) micromechanical PSH criteria & steady-state crack bridging, (2) precursor alkali activation mechanisms (FA, GGBS, MK), (3) fiber interfacial shear tailoring, (4) 3D concrete printing & digital extrusion, and (5) extreme durability under chemical/thermal actions.
- Synthesizes fiber reinforcement hierarchies, confirming that UHMWPE fibers achieve peak tensile strain capacities (5.0–12.0 %), PVA fibers provide cost-effective crack control (3.0–5.0 %), and hybrid/recycled fibers offer commercial scalability.
- Evaluates life cycle decarbonization metrics, showing that EGC reduces cradle-to-gate carbon emissions by 50 % to 80 % relative to Portland-based ECC.
- Establishes a strategic roadmap for industrial scaling: one-part solid activator EGC, low-carbon 3D printable composites, and smart self-sensing infrastructure materials.
Evidence summary
- Bibliometric Dataset: Over 1,200 peer-reviewed articles analyzed across co-authorship, institutional networks, keyword co-occurrence, and cross-citation mapping.
- Top Research Findings:
- Global Pioneer Leadership: University of Michigan (Victor C. Li), Southeast University, Tongji University, Curtin University, and Swinburne University.
- Core Knowledge Clusters: "Engineered geopolymer composite", "Pseudo strain-hardening", "Fly ash/slag activation", "Tensile ductility", "3D printing", "Durability".
- Performance Synthesis across Material Systems:
- Precursor blends: 60:40 to 80:20 FA:GGBS blends achieve optimal balance between ambient setting time and long-term strength ($f_c = 40\text{--}85\text{ MPa}$).
- Tensile ductility: PE-EGC achieves $\epsilon_u = 5.0\%\text{--}12.0\%$; PVA-EGC achieves $\epsilon_u = 3.0\%\text{--}5.0\%$.
- Environmental benefit: Up to 80 % reduction in carbon emissions and 60 % reduction in embodied energy vs. cementitious concrete.

Relationship to Victor Li book
- Extends Victor Li (2019) Chapter 4 (PSH Criteria), Chapter 7 (Fiber Systems), Chapter 8 (Optimization), and Chapter 9 (Green ECC, pp. 307–342).
- Serves as the macro-scale knowledge map tracing the evolution of Victor Li's micromechanics principles from original OPC-based ECC into global, zero-cement engineered geopolymer composite research.

Cautions
- Bibliometric reviews aggregate diverse laboratory testing protocols; direct numerical comparisons must account for differences in dogbone specimen geometries and loading rates.
- Liquid activator EGCs present on-site handling challenges; research is transitioning toward one-part solid activator dry-mix formulations.
