Paper Title:
Application of Fiber Bragg Grating Sensor to Monitor Early Age Deformation of High Performance Concrete
  Abstract

This paper presents a method to monitor the early age properties of high performance concrete (HPC) specimens successfully by embedded fiber bragg grating (FBG) monitoring system. The results show that the deformation increases rapidly within the first 30 hours after HPC casting. And its value is up to 65 µε and 84µε for two specimens respectively. As for the durability and permeability of HPC, early age deformation of HPC is pretty high and can not be neglected. Meanwhile, temperature compensation technique for FBG strain sensor has been put forward, and it is applied to measure early age deformation and temperature of HPC beam in situ simultaneously. The monitoring technique used here can be extended to concrete early age behavior monitoring in mass concrete structure with any size.
