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.

聚合物复合材料与混凝土表面的粘结强度是桥梁和停车结构的关键方面。在这项研究中，研究了不同尺寸的二氧化硅基材料增强的混凝土与聚酯复合材料之间的粘结强度。废弃的大理石粉尘/二氧化硅粉尘颗粒可以单独应用，也可以与纳米二氧化硅结合使用，形成聚合物复合材料，以增强粘合强度。倾斜剪切和劈裂拉伸试验结果表明，与纯聚酯复合材料相比，增强聚酯的粘合强度更高。废大理石粉尘与纳米二氧化硅和单一纳米二氧化硅的结合获得了最高的结合强度。此外，
