Material Property Research of High Performance Concrete on its early Age by Fiber Bragg Grating Sensor

Abstract:

In this paper, properties of HPC beam during the early curing period are studied by FBG embedded strain sensors. Since FBG senses both strain and temperature simultaneously, FBG temperature sensors are used to compensate temperature effect of FBG strain sensors for accurate measurement of strain. Meanwhile FBG temperature sensors can monitor inner temperature changes of concrete. Simultaneous measuring of strain and temperature has been realized here. The results show that early age autogenous shrinkages of HPC concrete beams during the early curing period are pretty high. Also the content of water reducing agent on autogenous shrinkage has been analyzed.
