Stabilization of expansive clay soil using shells based agricultural waste ash.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This study investigates the effectiveness of using various agricultural waste ashes-namely eggshell ash (ESA), clamshell ash (CSA), cockle shell ash (CKSA), and oyster shell ash (OSA)-for the stabilization of expansive clay soils (ECS). Laboratory experiments assessed the impacts of these ashes on the soil's consistency limits, shrink-swell behavior, compaction properties, unconfined compressive strength (UCS), shear strength, and mineralogical and microstructural characteristics. The results demonstrated that the inclusion of agricultural waste ashes significantly improved the ECS properties by reducing plasticity from 29.6 up to 7.84%, increasing shrinkage limit from 15.55 to 33.06%, reducing free sweeling index from 57 to 39.66%, and enhancing UCS and shear strength from 114.64 to 1509.95 kPa. Microstructural analysis revealed the formation of cementitious compounds that contributed to a denser and more robust soil structure. This research highlights the potential of these waste materials in sustainable soil stabilization, supporting environmental conservation and infrastructure resilience while aligning with Sustainable Development Goals (SDGs).
