INFLUENCE OF SIC-MICRO AND SIC-NANO ADDITIVES ON THE MINERAL BINDER HYDRATION PROCESSES

Abstract

One of the modern approaches to the mineral binder property improvement is the nanomodification problem solving based on a comprehensive approach to changing the material’s structure. The core idea involves the introduction of nanostructured elements and the use of surfactants (surface-active agents), which makes it possible to significantly enhance the physical and mechanical properties of the final material or even impart new, unique characteristics to it. This approach enables the hydration optimization and structure formation processes, opening up broad perspectives for the practical application of such modified binders. Nanoparticles, acting at the early stages of hydration, may change the gypsum crystallization morphology, regulate the crystal size and shape, and thereby directly influence the artificial stone structure, density, strength, and durability.

Purpose of the study: to identify the patterns of the gypsum binder structure formation mechanisms and to improve their physical and mechanical properties through the introduction of modifying nanoadditives and surfactants.

Currently, there are very few scientific studies dedicated to examining the combined influence of surfactants and nanomodifiers on the hydration processes and material structure, which highlights the relevance of further research in this field. The study discovers the impact of key factors on the hardening and structure formation processes of gypsum binders,determines the correlation between the additive nanoscale characteristics and the final material microstructural properties and proposes a theoretical model that explains the observed effects. All of this enables targeted control over the modification processes and the development of a new generation of materials with enhanced performance characteristics.
