The role of flaw size and fiber distribution on tensile ductility of PVA-ECC (2014, methodology): “For this purpose, a MATLAB program was developed and successfully utilized to obtain useful information about fiber distribution (dispersion and orientation) from the images captured by fluorescence microscope [17,19].”
Development of green engineered cementitious composites using iron ore tailings as aggregates (2013, methodology): “in one square (no dispersion at all) [19].”
Rheology, fiber dispersion, and robust properties of Engineered Cementitious Composites (2013, methodology): “Compared to the optical microscopic method and the X-ray method, fluorescence technology has a very high level of sensitivity to detect bright organic fibers that fluoresce under UV lighting from the dark surrounding cementitious matrix with a low background signal [47–49].”
