This article describes the technology of non-autoclaved aerated concrete production adding the fiber from polypropylene waste. This study investigates the development of a sustainable and high-performance non-autoclave aerated concrete by incorporating recycled polypropylene fibers derived from industrial waste. Traditional aerated concrete production often relies on energy-intensive autoclaving processes, however, this research explores an ambient-pressure curing method to reduce carbon footprint and production costs. The experimental program evaluates the influence of varying fiber concentrations on the physical and mechanical properties of the concrete, specifically focusing on compressive strength, thermal conductivity, and shrinkage behavior. By utilizing waste polypropylene fibers, the study aims to mitigate the inherent brittleness of non-autoclave mixes and improve crack resistance. Preliminary results indicate that the addition of recycled fibers significantly enhances the flexibility and ductility of the material compared to control specimens. Furthermore, the integration of waste materials contributes to a more circular economy within the construction industry. The findings suggest that polypropylene fiber modified non-autoclaved aerated concrete presents a viable, eco-friendly alternative for thermal insulation and lightweight structural applications in modern building technologies.
