Effect of Surface Modification of Steel Fiber on Concrete Comprehensive Performance

Abstract:

In order to investigate the influence of surface modification on concrete comprehensive properties, special electrodeposition process is applied to modify the surface of steel fiber. Then the modified fiber and the non-modified fiber are added into concrete for comparisive test and analysis. The results illustrate that the bond strength between the modified fiber and concrete increases about 50% when competing with the non-modified group. Besides, the crack area of non-modified fiber group declines 46% and the toughening effect rises approximately 30%.
