This paper presents a comprehensive study on the influence of the latest-generation superplasticizers andhyperplasticizers on the physical, mechanical, and operational characteristics of concrete mixes. Special attention ispaid to the comparative analysis of dispersion mechanisms: from the electrostatic repulsion of lignosulfonates andnaphthalene sulfonates to the steric stabilization effect of polycarboxylate-based admixtures. The research demonstratesthat optimizing particle distribution allows for a radical reduction in the water-cement ratio while maintaining highworkability and pumpability. A key aspect of the study is the evaluation of internal self-curing technologies. By forminga highly dense microstructure and utilizing specialized organomineral components, the necessity for traditional externalmoisture curing is minimized. The results confirm that the integrated use of chemical admixtures significantly improvesthe durability of monolithic structures, reduces plastic and drying shrinkage, and increases resistance to aggressiveenvironmental factors.
