Study of Properties of High Strength Concrete Reinforced with Industrial Waste Steel Fibers
High strength concrete (HSC) farther than high compressive strength, possesses uniform high density and very low impermeability, endowing itself with excellent resistance to aggressive environments and disintegrating agencies. But HSC has low flextural strength. Studies have shown that the lack of enough flextural strength of high strength concrete can be compensated by adding steel fibers to the concrete mixture. On the other hand one of the most important environmental problems is the majority of waste spiral steel chips, collected in industrial poles. In this study waste spiral steel chips have been used as steel fibers to reinforced high strength concrete. Also the properties of mixture have been studied. The main properties in this study are including slump of fresh concrete, density, compressive and bending strength of 28-days old specimens. The chips are classified into three different groups according to their shapes and three different categories of test are performed according to percentage of fibers in the mixture. The test results show that any increase in percentage of fibers, will increase the density of specimens and will decreases the slump of mixtures but it will result different behavior of their compressive and bending strength.
