含水率对路用水泥混凝土的影响及微波在线测湿系统

Influences of Water Content on Cement Concrete and the Microwave Moisture Measuring System

在讨论了含水率对路用混凝土质量的影响因素后，通过对不同种类测试传感器的分析，确定了较为适用的微波传感器，并给出了微波传感器的输出电压与集料含水率之间的关系式，进而对测试准确度进行了计算。

After the influencing factors of water content on concrete quality in pavement construction are discussed, through the analysis of various sensors, the microwave sensor is introduced. The relationship between the output voltage of microwave sensor and the water content of aggragate is given, the measuring accuracy is calculated.
