Abstract
This paper presents a discussion of work reported on properties of concrete prepared using industrial wastes as partial replacement of fine aggregate. Industrial wastes such as waste generated during mining and dressing of marble and granite; refining of zinc and lead waste i.e. jarosite, WFS (Waste Foundry Sand), broken glass waste, ISF (Imperial Smelting Furnace) slag, and Waelz slag as fine aggregate have been studied. The effect of these materials on compressive strength, flexural strength, water absorption, carbonation, sulphate resistance, chloride resistance and freeze thaw resistance were studied. The review of reported results indicated that the particle size distribution of industrial waste significantly influences the properties of fresh and hardened concrete. It was observed that replacement of natural fine aggregate with an industrial waste possessing particle size proximal to that of natural sand does not significantly alter the properties of concrete. Moreover, it was observed that waste materials that are finer than natural sand may have a negative effect on the properties of concrete. Majority of the waste materials indicated comparable to control compressive/flexural strength, resistance to water absorption, carbonation, sulphate attack, chloride ion permeability, and freeze-thaw properties of concrete containing waste materials as replacement of fine aggregate.
