Characterisation of Mortar Morphology in Thin Sections by Digital Image Processing

Digital image processing (DIP) is a computerized technique for image analysis that can be used in civil engineering for investigating materials, such as morphology of cements and clinkers, as well as the characterization of pore structure and microcracks in cement paste. This paper proposes a procedure for the determination of the mortar aggregate/binder ratio and grading curve on the basis of observation performed on thin sections, thus combining DIP methods with standard optical techniques. The results indicate that the imaging treatment may be an effective alternative to the traditional mechanical sieving.
