520			_aThe workability of concrete is a complex phenomenon that is equally difficult to measure. Extensive workability tests performed by various researchers are purely empirical. Neither of these methods measure workability in relation to the fundamental properties of fresh concrete. This paper proposes an analytical model to measure the workability of fresh steel fiber reinforced concrete. The model is formulated from the properties of the concrete components and can be effectively used to measure the workability of fiber mixtures in terms of reasonable applicability. An extensive experimental program was established to develop the model. Four (4) non-fiber and eighty (80) fiber-reinforced concrete mixtures were prepared and intensively studied to investigate the effects of variables such as cement content, coarse-to-fine aggregate ratio, fiber content, and fiber aspect ratio on the properties of fresh fiberreinforced mixtures. It was noticed that there is a significant effect of these variables on the properties of fresh and hardened concrete. Tremendous loss in slump was observed with increased fiber-matrix index in steel fiber-based concrete. The predicted model was compared with the experimental results of this study as well with the observations of some previously researched data. The model was found in good compliance with the experimental results and previously researched published data.
