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 the study of the flexural test of steel fiber concrete (SFRC) on 30 specimens in 90 groups, the influence of two different types and volume rates of steel fibers on the flexural strength of concrete is discussed, and the relationship between SFRC flexural strength, compressive strength and splitting strength is obtained, which provides reference for the application of bridge deck paving engineering of Nanyang Expressway. The results show that with the increase of steel fiber volume ratio, the flexural strength of SFRC also increases linearly, and the ratio of flexural strength to compressive strength also increases. The flexural strength of SFRC increased with the increase of splitting strength, but with the increase of steel fiber volume rate, the ratio of flexural strength to splitting strength of SFRC showed a downward trend.
