摘要
该文开展了人工海水环境下GFRP(玻璃纤维增强塑料)筋(玻璃纤维增强塑料筋)持续浸泡及干湿循环腐蚀试验,探讨研究了两种腐蚀方式对GFRP筋受压力学性能的劣化机理。研究结果表明:试件抗压强度随浸泡时间和干湿循环次数的增长基本呈线性下降;干湿交替循环腐蚀作用对GFRP筋受压性能的影响大于单纯氯盐溶液浸泡腐蚀;与碱溶液浸泡腐蚀数据对比可知,相同腐蚀条件下,碱溶液环境对GFRP筋抗压性能的劣化较氯盐溶液更为严重。
corrosion experiments of GFRP (Glass Fiber Reinforced Plastic) bars in artificial marine environment of continuous soaking and wet-dry cycling were carried out to study the deterioration mechanism of compressive mechanical properties. The results showed that compressive strength of the specimens decreased linearly with the increase of immersion time and wet-dry cycles during continuous soaking. The environment of wet-dry cycling had more effect on compression performance of GFRP bars than simply chlorine soaking. The effect of alkaline solution on the compression performance was more serious than chloride solution.
