Eco‐Sustainable Use of Industrial Wastes as Cement‐Partial Alternate in Concrete Composition

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
This study explores an innovative approach to enhancing the eco‐sustainability of concrete by incorporating industrial byproducts—cement kiln dust (CKD), silica fume (SF), steel slag (SS), and coal ash (CA)—as partial cement replacements. Unlike conventional studies that focus on single waste materials, this research uniquely evaluates the combined ...

Preparation of Semi‐Coke‐Based Porous Graphitic Carbon–Iron Oxide Composites and Their Electrochemical Performance for Rhodamine B Degradation

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
In response to the demand for clean production and high value‐added utilization of waste semi‐coke (SC) powder, SC‐based porous graphitic carbon–iron oxide (SPC‐Fe) composites were synthesized using a one‐step method with K2FeO4. The synthesis process primarily depends on the mass ratio of SC to K2FeO4 and the calcination temperature.
