Abstract

Micromechanisms of matrix fracture in Portland cement based fiber composites are studied by means of quantitative image analysis and acoustic emission technique. An experimental investigation has been conducted with different volume concentrations of polypropylene fibers. Uniaxial tensile specimens were loaded under constant strain rate and the acoustic emission response was monitored. Thin sectioned epoxydye impregnated samples were also prepared from specimens loaded to specified strain magnitudes. Fluorescence microscopy was used to quantitatively examine the thin sections for crack density, length, and spacing.
