Performance of Concrete with Mechanochemically Activated Rice Husk Ash-Based Organomineral Modifiers

This study evaluates a wet-activated multicomponent organomineral modifier for sustainable concrete. The modifier was produced by co-grinding Portland cement and rice husk ash (RHA) in the presence of Sika® ViscoCrete®-20HE and was subsequently combined with polypropylene fibers....

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...
