| 摘 要： | 研究了一种新型合成纤维-多微孔型的改性聚丙烯纤维对混凝土的孔结构及耐久性的影响。试验结果表明:在混凝土中掺入改性聚丙烯纤维可以明显改善混凝土的孔隙结构,在一定范围内,使其小孔百分含量增加,大孔百分含量减少,同时总孔隙率降低,因而改善了混凝土的抗冻性及抗渗性。

| Abstract: | The influence of a new synthetic fiber, porous polypropylene] on pore structure and durability of fiber reinforced concrete was studied in this paper. The results show that the pore structure of concrete may be markedly improved by the addition of oplypropylene fiber. The porosity of micro pore could be increased, and that of macro pore could be decreased.The total porosity could be reduced at the same time.So,The impermeability and frost resistance of concrete could be improved. |
