The bond strength of polymer composite to the concrete surface is a critical aspect of bridge and parking structures. In this study, the bond strength between concrete and polyester composites reinforced by silica-based materials of different sizes was investigated. Waste marble dust/silica fume particles were applied alone or combined with nano-silica into polymer composite to enhance the bond strength. Slant shear and splitting tensile test results showed that the bond strength of reinforced polyesters is higher in comparison with the neat polyester composites. The combination of waste marble dust with nano-silica and single nano-silica achieved the highest bond strength. In addition, it was observed that the addition of nano-silica and marble dust to the polymer composites showed a high load corresponding to low deformation in comparison with the other groups.
