摘要：

Measurement of moisture content (CH) of concrete aggregates (AOC) in the manufactury of ready mixed concrete is one of the currently challenges in the building industry since affect to the final properties of concret. At present, the methods for measurement of CH in AOC are invasive and destructive. This paper presents a novel sensing technique using dielectric espectroscopy (ED), a method that using the propagation of microwaves on the material allows the correlation of its dielectric constant (CD) and its CH. In this research is used this method in AOC. Three diferents peruvian quarries (Moyobamba, Sol sol y Cerro Mocho) have been used. The results shows that the sensor at the frequency of 1.5GHz is capable of detecting the CH in AOC with linear regression of R-2 = 95%. In conclusion, is available using the ED as a online and no invasive sensing method of CH in AOC for using in the building industry.
