Solar photovoltaic (PV) panels that use polycrystalline silicon cells are a promising technique for producing renewable energy, although research on the cells’ efficiency and thermal control is still ongoing. This experimental aims to investigate novel way improve power output performance by combining solar PV with burned fly-ash tiles. Made from burning industrial waste, torched fly ash has special qualities make it useful architectural applications. These include better insulation, strengthened structural integrity, high energy efficiency. Our test setup shows when combined tiles, generation rises 7% surface temperature decreases 3% compared standard panels. The enhanced ascribed outstanding insulation properties of tiles their capacity panel temperature. To ensure longevity safety in building applications, employed this study had water absorption rate 5.37%, flexural strength 2.95 N/mm2, slip resistance at 38 km/h.

Driven by the insatiable demand for construction materials, excessive quarrying natural aggregates and raw materials cement production pose significant environmental challenges, including habitat loss resource depletion. To address these concerns, this study investigates use of fibre-reinforced self-compacting concrete (FR-SCC) with high-volume fly ash (HVFA) varying levels recycled (RCA) as substitutes fine coarse aggregates. This approach aims to simultaneously concerns reducing reliance on virgin resources utilizing enhancing performance through combined benefits fibre reinforcement. In study, Self-Compacting Concrete (SCC) mixes were created 50% replaced conventional content, which was taken from previous literature. Fine aggregate utilized in investigation processed at 0% 100% an interval 25%, offering a promising solution alleviate burden associated while contributing sustainable practices. Additionally, replacement synthetic polypropylene fibres (PF) added into matrix up 1% 0.25%. research contributes development practices promoting efficiency minimizing impact. The found that SCC maintained self-compactability, improving workability cohesion. With combination highest strength value 55.31 MPa observed promotes

The aim of this study is twofold. First, to assess the effect sonication process on optimal dispersion GO sheets for nanostructural reinforcement cement pastes, as there currently no clear criterion in literature. For purpose, first stage, content distilled water was fixed at 0.03% by weight, and were dispersed using different levels ultrasonic energy, ranging from 0 J/mL 2582 J/mL. In second analyze modification pore structure due addition ratios (0–0.06% weight) its relationship with mechanical fracture properties reinforced pastes. According results, it has been determined that incorporation into matrix alters behavior, varying depending size particle size. leads a reduction average macropores (greater than 8 µm) 13% dosage 0.45% weight micropores (between 0.5 64% same composition non-sonicated GO, although total volume pores these ranges only decreased slightly. This more pronounced when not sonicated larger Sonicated primarily modifies range capillary (<0.5 µm). highest degree (465 nm) did show significant improvements compressive strength or Young’s modulus, used contains are substantially reduced any composition. Adding 0.030% ultrasonicated achieved 7.8% increase while an 0.045% resulted 13.3% decrease characteristic length, micropores.

Abstract Two-stage concrete (TSC) is a sustainable material produced by incorporating coarse aggregates into formwork and filling the voids with specially formulated grout mix. The significance of this study to improve predictive accuracy TSC’s tensile strength, which essential for optimizing its use in construction applications. To achieve objective, novel reliable models were developed using advanced machine learning algorithms, including random forest (RF) gene expression programming (GEP). performance these was evaluated important evaluation metrics, coefficient determination ( R 2 ), mean absolute error (MAE), squared error, root square (RMSE), after they trained on comprehensive dataset. results suggest that RF model outperforms GEP model, as evidenced higher value 0.94 relative 0.91 reduced MAE RMSE values. This suggests has superior capability. Additionally, sensitivity analyses SHapley Additive ExPlanation analysis revealed water-to-binder (W/B) ratio most influential input parameter, accounting 51.01% outcomes presented model. research emphasizes TSC design, enhancing performance, promoting sustainable, cost-effective construction.
