Abstract
In order to utilize Glass, Aramid and Carbon fibers as a reinforced material of concrete, alkali-resistance of each fiber was tested and computational model predicting the degragation of fiber was verified based on the experiments for alkali-resistance of fibers. Alkali-resistance of each fiber was compared from the view point of fracture strength and Young's modulus through the accelerated aging test in the alkaline solution. In addition, the degree of degradation of each fiber after aging test was investigated by Scanning Electron Microscope. As a result, it was concluded: (1) Glass fiber was easily degradated in the alkaline solution and the progress of degradation was stimulated quantitatively by the proposed method based on a diffusion theory, (2) both Aramid and Carbon fiber had a significant alkali-resistance without degragating.
