摘要:

研究了钢纤维对混凝土抗盐冻性能的影响，结果表明，钢纤维的掺入尽管使混凝土的抗折强度显著提高，但是却使混凝土的抗盐冻剥蚀性能降低，特别是引气混凝土抗盐冻剥蚀性降低得更明显。

Abstract:

Effect of steel fiber on the deicer-scaling resistance of concrete is investigated in this paper. Results show that the deicer-scaling resistance of concrete is reduced by the addition of steel fiber, especially for the air-entrained concrete, even the addition of steel fiber significantly enhances the flexural strength of concrete. The reason is that the good air-bubble structure of concrete is damaged due to the addition of steel fiber.
