Nanomaterials, as a new type of functional material, are widely used in concrete modification to enhance its mechanical properties and durability. This article systematically studies the influence mechanism of nanomaterials on the microstructure of concrete, and analyzes the improvement effect of different nanomaterials on the compressive strength, flexural strength, and durability performance of concrete. By combining experimental and theoretical methods, the dispersion state and reinforcement mechanism of nanoparticles in concrete were revealed, and a technical path for optimizing the concrete mix ratio was proposed. Nanomaterials can effectively improve the density and chemical resistance of concrete, significantly prolong the service life of structures, and provide theoretical basis and practical guidance for the high-performance design of concrete materials.
