Abstract

In order to improve the application effect of steel fiber reinforced concrete (SFRC) in road bridge construction, the mechanical properties of SFRC with different fiber content were analyzed. The SFRC specimens with 0%, 0.5%, 1%, 1.5% and 2% fiber content were designed, and the mechanical properties were tested. The results showed that the compressive strength first increased and then decreased with the increase of fiber content, and the maximum compressive strength of SFRC1.5 reached 40.86 MPa, increasing by 7.19%; the increase amplitude of tensile strength of SFRC1.5 was 73.04%, which was the most obvious; the flexural strength of SFRC increased with the increase of fiber content, and the flexural strength of SFRC2 was 9.78 MPa, increasing by 94.43%. It is concluded from the experimental results of a case study that SFRC1.5 presents the optimal overall mechanical properties and is more suitable for road bridge construction.

道路桥面施工中钢纤维混凝土材料的力学性能
为了提高钢纤维混凝土在公路桥梁施工中的应用效果,对不同纤维含量的钢纤维混凝土的力学性能进行了分析。设计了纤维含量分别为0%、0.5%、1%、1.5%和2%的SFRC试件,并对其力学性能进行了测试。结果表明,随着纤维含量的增加,SFRC1.5的抗压强度先增大后减小,最高抗压强度达到40.86MPa,提高7.19%;SFRC1.5的抗拉强度增幅最大,为73.04%;SFRC2的抗弯强度为9.78MPa,提高了94.43%。实例试验结果表明,SFRC1.5具有最佳的整体力学性能,更适合公路桥梁施工。
