        abstract = {The aim of this study is to develop a lightweight polyurethane foam concrete that delivers improved strength and long-term durability through the combined use of nano silica and basalt fibers. The work builds on the need for structural materials that reduce self-weight while maintaining reliable performance, especially in environments where moisture related deterioration limits service life. The methodological framework involves preparing mixes with controlled variations in nano silica and basalt fiber content, followed by a structured sequence of compressive, flexural, water absorption and sorptivity tests to understand how each modification influences the behavior of the material. This approach produced clear results, with the most enhanced mix reaching a compressive strength of 17.9 MPa, a flexural strength of 3.1 MPa, and a reduction in water absorption to 8.3 percent, showing how the combined modifiers improved both mechanical and durability performance. The study concludes that integrating nano silica for matrix refinement and basalt fibers for internal reinforcement creates a synergistic effect that strengthens the foam concrete and reduces its vulnerability to moisture, offering a practical pathway for producing lightweight concretes with better long-term stability.},
