混凝土结构使役环境中氯离子浓度控制系统设计

本文结合湖北省自然科学基金项目混凝土结构使役环境的智能模拟(2008CDB396),在前期211工程项目单轴约束可调式混凝土温度应力试验机研究基础上,针对现有混凝土耐久性试验机在侵蚀溶液注入与氯离子浓度控制环境的空白,采用C51单片机为控制器,设计了一种混凝土结构使役环境中氯离子浓度控制系统,用于自动调节混凝土耐久性实验,模拟实验环境箱内的侵蚀溶液氯离子浓度,保证混凝土耐久性实验试件所处环境氯离子浓度稳定在设定的范围。系统采用溶液缓冲调节与循环注入方式,控制单元采用直读式离子浓度控制器,信号采集更方便。本系统不仅结构简洁,工作可靠性高,还能减少人力浪费,提高运行经济性。
