Sustainable engineered cementitious composites incorporating recycled materials: Experimental validation and life cycle assessment.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The use of recycled constituents in engineering cementitious composites (ECC) offers a promising pathway to reduce the environmental burden of cement-based materials while maintaining high mechanical performance. In this study, recycled concrete powder (RCP) and waste tire steel fiber (WTSF) were incorporated into ECC, and their mechanical and environmental performance was evaluated through experimental testing, Digital Image Correlation (DIC), Scanning Electron Microscopy (SEM) and life cycle assessment (LCA). DIC was used during flexural testing to quantify surface deformation and characterize crack initiation and propagation, while SEM was employed to evaluate fiber-matrix interaction, microstructural features, and crack-bridging mechanisms. A cradle-to-gate LCA was compare the environmental impacts of cement, RCP, industrial steel fibers, WTSF, and sustainable ECC mixtures. The experimental results show that the sustainable ECC mixtures maintained competitive flexural performance, with the highest flexural strengths reaching 44.5 MPa for a mixture containing 2% WTSF and 43.5 MPa with 2% polyethylene fiber. The LCA results for the complete sustainable ECC mixtures demonstrated reductions in climate change potential and fossil resource consumption compared with conventional ECC mixtures. These findings demonstrate the potential of recycled-material-based ECC to support sustainable, low-carbon, and circular construction practices without compromising structural performance. Overall, the findings support RCP and WTSF as effective low-carbon alternatives for ECC, enabling improved sustainability without compromising structural performance.
