Strengthening construction materials using nanopowders opens new possibilities for creating stronger, more durable, and sustainable structures. This research direction is actively being explored and developed, enabling the implementation of innovative solutions in the con-struction industry and improving the quality of building materials. To enhance the mechanical, thermal, and other properties of polymeric materials, nanopowders of metal oxides, carbides, graphene, and carbon nanotubes are introduced into the matrix. The use of tungsten-based nanopowders represents a relevant task that, in the long term, can address the limitations of existing technologies and expand the application areas of these compounds for creating new materials. Previously, the use of such particles was economically unfeasible for modify-ing cement and concrete matrices, ceramics, and composites based on aramid and fiberglass fabrics. The aim of this study was to investigate the possibility of using tungsten-containing nanopowders obtained through the processing of hard-alloy waste via a technology that is more economical and simpler compared to existing analogues, and to consider potential applications of these powders as modifiers. Tungsten-containing nanopowders were produced using a patented method that differs from analogues by the high purity of the resulting powder, min-imal production costs, and negligible impact on the natural environment. This article presents possible applications of tungsten-containing nanopowders as modifiers. It is demonstrated that such powders can significantly improve various operational properties of "conventional" construction materials due to their low production cost. This enables the development of innovative materials capable of meeting growing and diverse demands.
