The concept of nanotechnology and its role in construction materials

Abstract

This article examines the scientific essence of nanotechnology, its place in construction materials science, and its significance in improving modern construction materials. Nanotechnology is based on the control of structures and processes within the range of 1-100 nm; therefore, it can strongly influence the surface activity, reactivity, and microstructure of materials [1]. In construction materials, especially cement-based composites and concrete, nanomaterials can accelerate hydration, densify the pore structure, strengthen the interfacial transition zone, and improve mechanical as well as эксплуатацион durability-related properties [2-4]. The paper also considers the effects of nano-silica, titanium dioxide, carbon nanotubes, and other nano-additives on the properties of construction materials, as well as the advantages and limitations of their practical implementation [3-6].
