【 摘 要 】

Currently, inclusion of technogenic materials as components of new generation concretes (NGC) attracts attention of researchers and engineers from various countries. Wide application of high-strength concretes with increased cement stone content, fineness of binder and aggregate particles, multi-component composition, facilitates improvement in concrete articles quality and further industrialization of the construction production. Due to that, it appears timely to study condition of structural formation of high-strength concrete, a role that technological factors play in this process and its substantial composition. The paper consider some aspects of designing a composition and a production technology for NGC articles, as well as their relevance in modern construction. Results of compositional and technological analysis of high-strength concretes produced with nanostructured modifiers having various chemical and mineral composition and genesis are given. Possibilities are found to reduce binder consumption by introducing technogenic and organic feed; to provide lower consumption of material resources and energy; to employ non-toxic, non-combustible and environmentally-friendly materials.
