摘要
混凝土氯离子渗透性是评价混凝土耐久性的重要指标,氯离子渗透性检测是保证混凝土质量的重要手段.为了准确的测定混凝土的氯离子渗透性,研制了基于电量法的氯离子渗透性检测系统.系统由硬件系统和上位机分析软件构成.硬件系统是基于单片机的采集系统,通过上位机实现数据的采集分析处理.系统已应用于实践,使用结果表明,系统精度高、操作方便、性能良好.
Chloride ion permeability in concrete is important index to evaluate durability of concrete, and its testing is critical means to ensure concrete quality. In this paper, a testing system is designed to measure chloride ion permeability exactly, which comprises hardware system and analyzing software of PC. The hardware system is collection system based on singlechip, and the software system collects, analyses and disposes the data. After its application into practice, this system proves to be precise, convenient and of good performance.
