In this work, the digital image correlation (DIC) technique was used to evaluate the fiber cement deformation process. The composites were produced with partial replacement of cement by construction and demolition waste (CDW), in the contents of 0, 5, 10, and 15% by mass, and 10% of eucalyptus kraft pulp bleached by the slurry-dewatering and pressurization method. After the curing process, the fiber cement was subjected to bending at four points and monitored by cameras, responsible for photographic records every 2 seconds. The composites were analyzed with image correlation technology, where the deformation stages of the composites could be observed. In general, through the use of the DIC technique, it was possible to identify regions of greater deformation, areas of stress concentration, and possible failures or critical points, in addition to having enabled the identification of the failure mode of the composites.
