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

The negative environmental impact of high cement use and aggregate extraction can be minimized by the use of greener materials and recycled aggregate (RA) instead of conventional materials. In this study, the effects of a low-calcium bentonite (LCB) binder on the strength development and workability of recycled aggregate concrete are investigated. RA is used as 0, 50, and 100% by volume replacement of natural aggregate concrete (NAC), whereas bentonite is used as 0, 5, 10, 15 and 20% by weight replacement of cement for each level of RA. LCB addition significantly improved the 90-day compressive, flexural, and splitting tensile strengths of normal and RA concrete, whereas at 28 days, the results of the LCB mixtures were comparable to those of the control. The RA mixtures had slightly reduced compressive strengths, similar tensile strengths, and superior flexural strengths to those of NAC after 90 days. Higher correlations between all strength results with successively higher RAs. These results can be attributed to the pozzolanic properties of LCB and their symbiotic relationship with the mortar adhered to the surface of the RA, along with greater bonding surface regions for the cement matrix. The response surface methodology (RSM) confirmed the trend in strength.
