Thermal Conductivity in Mortar Samples with Copper Mine Tailings.
Article in Materials (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 increasing generation of mine tailings poses significant environmental challenges, but their reuse in construction materials offers a sustainable solution by reducing the demand for natural aggregates. To advance the use of tailings in construction, the thermal conductivity of mortar samples incorporating copper mine tailings as partial replacements (10% to 50%) for coarse aggregates was investigated. The thermal conductivity was measured using the transient line source method, revealing a progressive increase from 0.32 W/m·K (control sample) to 0.52 W/m·K (50% replacement sample). The statistical analysis (ANOVA) confirmed significant differences among the sample groups, with the tailings content being a key factor. The higher thermal conductivity is attributed to the quartz-rich composition of the tailings, which enhances the heat transfer compared to conventional aggregates. The findings of this study contribute to demonstrating the feasibility of using mortar with copper tailings to modify the thermal conductivity of mortar.
