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

High-strength concrete (HSC) has been extensively studied for major applications, particularly in high-rise buildings and bridges. Furthermore, conductive concrete exhibits enhanced electrical properties, enabling its use in specialized applications such as heating, electromagnetic shielding, and antistatic systems. This study aims to combine these two types to produce conductive high-strength concrete (CHSC) using locally available materials. The proposed mixes' performance measurements include compressive strength, flexural strength, modulus of elasticity, long-term effects (like creep and shrinkage), and electromagnetic shielding. HSC with compressive strength up to 100 MPa and modulus of rupture of 8.96 MPa was successfully produced using locally available materials. The mix containing low dune sand achieved the best mechanical performance. The inclusion of steel fibers (FLDUNE) increased 28-day compressive and flexural strengths by 3.5 and 22%, respectively, and reduced shrinkage and creep by 25 and 10%. However, the addition of carbon materials along with steel fibers (FCLDUNE) decreased these strengths by 19.6 and 15%, and increased shrinkage and creep by 18 and 9%, respectively. The measured electrical properties of the proposed concrete mixes show resistivity of 33.3 Ω-m for FLDUNE and 25.7 Ω-m for FCLDUNE mixes and measured relative complex permittivity of 22.57-j2.22 with relative complex permittivity of 22.57-j2.22. Electromagnetic shielding showed an attenuation of -70 dBm using steel fiber, compared to -28.3 dBm for the control mix. Adding carbon material with steel fiber did not provide significant added value for shielding applications.
