000004960 520__ $$2eng$$aElectronic Speckle Pattern Interferometry technique is used to record the location of crack initiation, sequence of the multiple cracking and recording the cracking stresses of the fiber reinforced cement composites. Microstructural parameters at each crack location are quantified by statistical methods. The size of the fiber free areas are measured and percantage of fiber clumping are calculated at the crack surfaces. Relation between the microstructural parameters and mechanical performance is invesigated. It is found that increase in the size of the fiber free areas in the composite decreases the cracking stresses. It is shown that the toughness of the composite depends on the fiber clumping at the first crack cross-section.
