One Monitoring Device for Concrete Early Age Shrinkage
With liquid as transmission medium, using ultrasonic precision measurement, an effective device was studied and developed for monitoring early age shrinkage of concrete. With it, shrinkage of concrete in the plastic stage could be accurately monitored. During the measurement, 0.01mm and even higher monitoring accuracy could be achieved.
