Experimental Research on Abrasion Resistance of Steel Fiber-Reinforced Concrete Based on Response Surface Method

To address steel fiber cement concrete pavement abrasion problems, the response surface method of the Design Expert 7.0 software is used to analyze the effect of aspect ratio of steel fiber, steel fiber volume-adding rate, and water-cement ratio on the abrasion resistance of steel fiber-reinforced concrete. The steel fiber concrete abrasion resistance model and optimization prediction model are built. Regression analysis and variance analysis are performed on the model. The model represents lack of fit at P=0.066 6>0.05, which indicates that the model’s lack of fit does not show significant difference. The test data and model are irrelevant and insignificant. The multiple correlation coefficient R² is 0.986 6. The actual test difference degree is 0.013 4, and the optimization results of the solving model are unknown. When the steel fiber slenderness ratio is 56.24, the steel fiber mixing rate is 1.34%; the water-cement ratio is 0.37; and the abrasion resistance of steel fiber-reinforced concrete is the optimum. The difference between the testing value and the theoretical prediction is not significant. The response theory analysis of the actual situation can be fit for steel fiber-reinforced concrete abrasion surface analysis.
