摘要: Abstract Fracture patterns produced when a crack advancing from notch in cement paste intersected Cem FIL-2 glass fiber strand placed perpendicular to it were studied. The specimens small notched compact tension that could be wedge loaded the scanning electron microscope chamber using wet cell. Four distinct cracking identified. In most cases caused shift path and some specimens, microcracking separation of into 2 4 branches observed. filaments maintained their continuity bridged over track. Similar tests with E-glass fibers after accelerated curing revealed brittle behavior which was straight many broken.
