Experimental Dataset on Evaluation of the Abrasion Resistance of Polymer Concrete Using Colloidal Nano-Silica and Nano-Alumina Solutions

Abrasion is a major cause of reduced durability in hydraulic concrete structures, resulting from surface wear due to high-velocity water flows carrying suspended solid particles. The extent of damage depends on factors such as particle properties, flow velocity, and concrete quality. Recent studies indicate that polymer admixtures and nanomaterials can significantly enhance concrete’s resistance to abrasion. This study examines the combined effects of colloidal nano-silica and nano-alumina solutions with styrene–butadiene rubber (SBR) polymer latex on concrete abrasion performance. Concrete specimens containing 0%, 5%, 10%, and 15% SBR were prepared and tested using the ASTM C1138 abrasion method. Nano-solutions were applied to the surface by spraying, and steel shot was used to simulate abrasive suspended solids. Abrasion depth and time-dependent wear behavior were evaluated over four hours. Results showed that increasing nano-particle content reduced abrasion rate and wear depth, improving surface resistance. Nano-silica performed better than nano-alumina. Abrasion resistance increased with SBR content up to 10%, but higher dosages reduced performance due to increased porosity from air-entraining effects. These results suggest that surface-applied nano-solutions combined with optimal polymer dosage effectively enhance concrete durability in aggressive hydraulic environments.
