Composite materials such as Fiber Reinforced Cement or Concrete (FRC) are designed to prevent brittle fracture. FRC is characterized by enhanced ductility and distributed crack formation prior to failure. Mitigation of progressive crack propagation and localization of cracks and stresses are result of the even distribution of fibers throughout the matrix. This chapter presents the utility of full field optical methodology for tracking the progressive development of cracking in cement based FRC. A full field imaging approach is used to better understand the link between microstructural properties, and sequence of cracking. We present the application of Electronic Speckle Pattern phase measurement interferometry (ESPI) for the identification of crack locations, size and progression, and how these features are linked to the uniformity of fiber distribution in the matrix.
