【 摘 要 】

Recycling of waste materials limit solid wastes and saves natural resources. The investigations of using waste materials in concrete mixtures increase day by day. Use of waste materials in concrete gave economical disposal of wastes. This paper investigates the possibility of using metal wastes strips resulting from civilian factories of domestic storage tanks as fibers and its effect on some concrete properties which include workability of fresh concrete, compressive strength, splitting tensile strength and flexural strength. Five concrete mixtures with different ratios of metal wastes fibers, (0, 0.5, 1, 1.5 and 2) % of concrete volume have been added to produce the concrete composites. Three Cubes, cylinders and prismatic samples have been made for compressive, tensile and flexural strength tests respectively for each mixture. The mechanical properties of mixtures were analyzed in comparison to the control mixture. The results showed that the metal waste fibers could be used successfully to enhance the mechanical properties of concrete. An increase in metal wastes fibers content led to increase in strength properties of concrete, and the optimum percentage of metal wastes fibers for strength improvement are ranged between 1.0-2.0%.
