摘要
设计采用钢筋混凝土水池将振动与盐溶液耦合,研究了振动作用对模拟海洋环境中高性能混凝土劈裂抗拉强度与抗氯离子渗透性能的影响。结果表明:在振动作用下,混凝土劈裂抗拉强度略有增长,模拟浪溅区与模拟水下区混凝土劈裂抗拉强度随浸泡深度增加而增大。振动作用导致混凝土氯离子渗透深度增大,且模拟浪溅区混凝土氯离子渗透深度大于模拟水下区混凝土氯离子渗透深度;不同浸泡深度混凝土中氯离子浓度均在振动作用下有所增大,且模拟浪溅区混凝土中氯离子浓度大于模拟水下区混凝土中的氯离子浓度。
Effect of vibration on splitting tensile strength and chloride penetration resistance of high-performance concrete(HPC)in simulated marine environment was investigated by using reinforced concrete pool to couple vibration with salt solution.The results showed that the splitting tensile strength of HPC increased slightly under vibration load.The splitting tensile strength of HPC increased with increasing depth of immersion in the simulated splash zone and the underwater area.The vibration causes the increase of the penetration depth of chlorine ions into increase,and the penetration depth of the chloride ions in simulated splash area is greater than that in simulated underwater area.The concentration of chloride ions in different immersion depth was increased under the vibration load,and the concentration of chloride ions in various depth of the HPC in simulated splash area was greater than that in concrete in simulated underwater area.
