Abstract: 
Steel fiber concrete is being used to improve plastic cracking characteristics, tensile and flexural strength, impact strength, and post cracking behaviour. Many guidelines by ACI 544 committee and steel fiber producers are available to provide directions for proportioning and mixing of steel fiber in concrete. In addition, recommendations and other mixing tips are given to avoid balling during mixing to ensure uniform distribution of the steel fiber in the mix. However, many concerns have been raised about the fiber distribution especially when a higher ratio of the steel fiber is used.
This paper will discuss an approach, which was followed during the evaluation of a steel fiber concrete mixture to ensure homogeneous distribution of the fiber within the mixture. In addition, summary of the mechanical properties of the mixture will be discussed.
