文章所述的实验采用混凝土试块浸泡试验,并定期检测混凝土表面的氯离子浓度,得出氯离子浓度的大小和累积速度与混凝土强度、氯盐溶液浓度及时间的关系,结合五个模型拟合相关数据,得出混凝土表面氯离子浓度随时间的变化规律。实验结果显示,混凝土表面的氯离子浓度随时间的增加呈递增趋势,后速率放缓,逐渐达到稳定状态。
The experiment described in this article uses the concrete block immersion test, and periodically tests the chloride ion concentration on the concrete surface to get the relationship between the chloride ion concentration and the accumulation velocity and the strength of concrete, the concentration and time of the chloride salt solution. Combining the five models Combined with the relevant data, come to the concrete surface chloride ion concentration changes with time. The experimental results show that the chloride ion concentration on concrete surface increases with the increase of time, and the post-rate slows down and gradually reaches a steady state.
