Tests were carried out with two types of steel fibers to evaluate their restraining capability in shrinkage-compensating concrete. The effect of the fiber reinforcement on compressive flexural strength and modulus of elasticity was investigated. The results indicate that steel fibers can be successfully used for restraining shrinkage-compensating cement. Inclusion of fibers in concrete improved the compressive and flexural strength of both plain and conventionally reinforced shrinkage-compensating concretes. The differences in the moduh were insignificant for practical purposes. Concrete containing bent fibers showed less restrained expansion and higher flexural strength when compared to concrete with straight fibers.
