摘要:
通过10%硫酸钠溶液加速劣化试验,研究CFRP-混凝土粘结界面的力学性能,包括混凝土圆柱体的抗压强度、 CFRP片材的拉伸强度、混凝土的抗压强度及弹性模量.通过CFRP-混凝土粘结界面的单剪试验,研究硫酸钠溶液浸泡对CFRP与混凝土剪切粘结性能的影响,采用SEM和XRF等从微观层面探讨硫酸盐腐蚀机理.研究表明,硫酸钠溶液浸泡对CFRP的拉伸强度无影响;混凝土会受到硫酸盐的侵蚀,侵蚀程度与浸泡时间相关;因树脂的保护作用,10%硫酸盐溶液腐蚀118d对CFRP-混凝土界面的粘结性能基本无影响.
Abstract:
This paper investigates the behaviors of adhesive bonded CFRP-concrete joints under the accelerated aging test of 10% sodium sulfate solution.The tensile strength and ductility of CFRP,the elastic modulus and cylinder strength of concrete,and shear bonding strength were evaluated.This paper also tried to explain the attacking mechanism of sulfate solution via the microscopic technology,i.e.SEM and XRF.Results shows that the sodium sulfate solution has no effect on the CFRP composite.The concrete deteriorates over time is due to sodium sulfate solution.The bonding behavior of CFRP-concrete joints has not degenerated immersed in sodium sulfate solution for 118 days.The reason is that the concrete beneath the CFRP composite was protected by the resin against sulfate solution attacking.
