Tests were conducted using a ring-type specimen to simulate restrained shrinkage cracking. The effects of two types of fibers (steel and polypropylene); differing amounts of fibers (0.1 to 1.5 percent by volume); age of concrete (2 hr or 4 days); and length of drying (up to 6 weeks) under a given environment [40 percent relative humidity and 20 C (68 F)] were studied. The results were satisfactorily compared with a theoretical model developed by the authors.
