Improving New Generation Concretes (NGCs) by Introducing Technogenic Materials

Abstract

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.
