Structural and rheological design of self-compacting fine-grained concrete for vibration-free casting

This study investigates the development of Self-Compacting Fine-Grained Concrete (SCFGC) optimized for vibration-free technology. By utilizing polycarboxylate superplasticizers and mechanically activated mineral fillers, the research achieves precise control over rheological properties and structural viscosity (reducing it by up to 41 %). Based on Uzbekistan’s CEMI 32.5N Portland cement, the interaction within the “cement-filler-water” system enhances the cement stone microstructure, ensuring high durability and dense structure formation. This approach significantly improves energy efficiency, enables noise reduction, and lowers labor intensity, offering a sustainable solution for modern monolithic and prefabricated construction.
