In this paper,a cement-based magnetoelectric(ME)laminated composite is fabricated by bonding the piezoelectric material lead zirconate titanate(PZT)between two C-M layers made of the mixture of cement and magnetostrictive material to form a sandwich structure.As well known,inherent measurement errors of traditional electric sensors are definitely induced by magnetic interference in magnetic field.Thus,it is impossible to measure the magnetostrictive strain due to a variable magnetic field.In this paper,the fiber Bragg grating(FBG)sensors were used instead of the traditional strain gauges to measure the strain of the cement-based magnetostrictive layers in a variable bias magnetic field.It can be concluded that the FBG sensors is a reliable choice as its tiny size,high sensitivity and immunity to magnetic interference.
