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