Mechanical Performance, Durability, and Microstructure of Dune-Sand Concrete Incorporating Rice Husk Ash and Dried Oil Sludge

This study evaluates sustainable dune-sand concrete produced using local dune sand, rice husk ash (RHA), and dried oil sludge. The experimental program included a control mixture (C0) and three modified mixtures (M1–M3). RHA was used as a partial replacement for Portland cement a...
