Effects of steel fibers on the deicer-scaling resistance of concrete were investigated in this paper. Results show that the deicer-scaling resistance of concrete is reduced by the addition of steel fibers at the same air content, especially for the air-entrained concrete, even though the flexural strength of concrete is significantly improved by the addition of fibers. The reason is that the average air-void spacing factor of concrete becomes larger due to the addition of steel fibers. The variations in the deicer-scaling resistance among the different concrete qualities can be fully explained by the spacing factor values. (c) 2005 Elsevier Ltd. All rights reserved.
