INCORPORATION OF INDUSTRIAL IRON WASTES AS INGREDIENTS IN MAKING ENERGY EFFICIENT CONCRETE

Abstract :

 Utilization of industrial soil waste has been encouraged in construction field for the production of concrete because it contributes in reducing the consumption of natural resources. The metal–casting industries called foundry generates enormous amount of by– products such as used foundry sand and iron dust. In the meantime the global demand for concrete increases annually. This demand leads to the over consumption of natural resources for manufacturing both cement and aggregates. So it not only results in exploitation of nature but also in polluting the environment by emitting carbon dioxide. To overcome these problems, using foundry sand as partial fine aggregate and iron dust in form of iron based cementitious material as the replacement in various proportions for conventional cement are suggested. These suggestions are examined and compared with properties of conventional concrete. The investigations were carried out in the form of Compressive strength, Split Tensile strength, Ultrasonic Pulse Velocity test, Rapid Chloride Permeability Test, Sorptivity test and Water Absorption test were conducted in concrete. The results show that the partial replacement gives appropriate strength as the conventional mix. It also identified that 10% replacement of cement by iron based cementitious material and 20% replacement of river sand by foundry sand as the optimum percentage of replacement in reinforced concrete to increase the strength and corrosion resistance.
