Wear resistance is one of the main properties of road and bridge concrete, and improving the wear resistance of concrete is of great significance to ensure its durability. Based on the ash entropy method, the author analyzes the significance of the factors affecting the wear resistance of fly ash concrete, and the analysis results show that the influence of water consumption and aggregates is significant, followed by cement dosage, and the influence of fly ash content is minimal, which can provide scientific basis for the design of fly ash concrete with wear-resistant requirements. The theoretical derivation of ash entropy method is relatively strict, the calculation is simple, and the size of ash entropy correlation is not affected by the resolution coefficient, which can overcome the shortcomings of the general gray correlation method, and achieve more ideal results when analyzing the significance of each influencing factor.
