| 摘 要： | 通过对30组共90个试件进行的有关钢纤维混凝土(SFRC)抗折试验的研究,着重讨论两种不同类型和不同体积率的钢纤维对混凝土抗折强度的影响,得出SFRC抗折强度与抗压强度、劈拉强度等之间的关系,为南阳高速公路桥面铺装工程的应用提供参考.研究结果表明:随着钢纤维体积率的增大,SFRC的抗折强度也随着线性提高,抗折强度与抗压强度之比也随着呈上升趋势;SFRC抗折强度随着劈拉强度的提高而提高,但随着钢纤维体积率的增大,SFRC的抗折强度与劈拉强度比呈下降趋势.

| Abstract: | Through studying a total of 90 specimens divided into 30 groups in the flexural test.and through studying on the flexural strength of steel fibers concrete,this paper uses different Vf and two types of steel fibers in concrete to study the influence to the flexural strength.And it studies the relationship of flexural strength,compressive strength and splitting strength.And it provides reference to practice concrete pavement of Nanyang expressway project.The results show that the flexural strength and the ffc,m/ffc,cu increase with the increase of Vf.The flexural strength increases with the increase of splitting strength,but the ffc,m/ffc,spl decrease with the increase of Vf. |
