Title: Factors Affecting the Flexural Strength of Steel Fibrous Concrete
Strength of Steel Fibrous Concrete
Author(s): M. Jack Snyder and David R. Lankard
Publication: Journal Proceedings

Abstract:An investigation was made of the effects of steel fiber parameters and concrete mix parameters on the flexural strength properties of steel fibrous concretes and mortars. Compositions were evaluated in which the steel fiber content was as high as 4.0 volume percent. Data are presented which show the relationship of fiber content and fiber spallng on the ultimate and first crack flexural strength of a standard mortar formulation. The effect of mix workability as controlled by the mix composition on the flexural strength properties is discussed. The effect of coarse aggregate additions on the flexural strength of a steel fibrous mortar is also discussed. The use of steel wire fibers provides significant improvements in the flexural strength properties of concretes and mortars when the proper conditions of mix formulation, batching, and placing are achieved.
