【摘要】 本文对SFCB增强海砂混凝土梁的短期性能和海水干湿循环下SFCB增强海砂混凝土梁的长期性能进行了试验研究,并和同等条件下的钢筋增强海砂梁进行了对比研究。试验结果表明,SFCB增强海砂混凝土梁具有良好的力学性能,并表现出了明显的二次刚度。在经历长期干湿循环后,与钢筋海砂梁相比,SFCB增强海砂混凝土梁拥有更优秀的耐腐蚀性能。更多还原

【Abstract】 In this paper, the short-term flexural properties of SFCB reinforced marine sand concrete beams and steel beams were first testedand the effect of dry-wet cycling with sea water on them were comparative studied. The test results showed that SFCB reinforced marine sand concrete beams had excellent mechanical properties and presented obvious secondary stiffness.Compared with steel beams, SFCBbeams presented obvious corrosion resistance afterwet-dry cycling.更多还原
