短纤维对抗冻劣化特性影响的研究

A study on influence of short fiber over the freezing-resistant and deterioration-resistant property of cement-based material

采用真空成型的手段 ,大大减少了纤维的引气性 ,来研究短纤维对水泥基材料的抗冻劣化性能的影响。冻融实验结果表明 ,短纤维虽然不能完全阻止材料的劣化 ,但是却延缓了冻融破坏的速率。

Vacuum moulding was used for the study on influence of short fiber over the freezing\|resistant and deterioration\|resistant property of cement\|based material. Freezing\|thawing test shows that short fiber can not stop deterioration of materials, but can retard freezing and thawing action.
