1 · What the graph read from it

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.

2 · The registry

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

Grouting techniques are used in retrofitting structures to improve the structural integrity and performance of existing structures. The recent era of nanotechnology enabled the development of high-performance nanocomposite based cementitious grouts, epoxy grouts, and polyurethane grouts which enhance the strengths, durability, and life span on structures. However, use of only nanocomposite cement grouting is inadequate to bridge micro-cracks, densify the interfacial transition zone (ITZ) after retrofitting. In this study, a novel two-step hybrid crack restoring approach for concrete structures is introduced by combining injected Multi-Walled Carbon Nanotube (MWCNT) reinforced cementitious grout for nanoscale crack-bridging and ITZ densification with an epoxy coating for surface sealing for treating cracks as an integrated nano-micro-surface system. The main objective of the study is improving the mechanical performance and structural integrity of retrofitted concrete structures by assessing their synergistic effect on load-carrying capacity, deformation, and durability. The experimental study is carried out to evaluate the mechanical properties such as load carrying capacity, stress, strain, ductility, sulfate attack and influence of elevated temperature. The results demonstrate that the rupture strength of crack-restored specimens increased by 27.27, 33.33, and 20% compared to plain concrete specimens subjected to controlled room temperature, elevated temperature of 400 °C, and sulfate exposure, respectively. The microstructural analysis reveals that nanoparticle fill-up cracks in the cement composite, enhancing interaction at the interfacial zone. This study highlights the effectiveness of nanomaterial-infused grouting techniques as an innovative and efficient solution for structural retrofitting by offering improved strength, longevity, and resistance to environmental conditions.
