Abstract:
Tests were conducted using a ring-type specimen to simulate restrained shrinkage cracking. The effect of two types of fibers (steel and polypropylene), amounts of fibers (0.1 to 1.5 percent by volume), age of concrete (2 hr or 4 days), and period of drying (up to six weeks) under a given environment {40 percent relative humidity and 20 C (68 F)} were studied. The results were compared satisfactorily with a theoretical model developed by the authors.
