Concrete is widely used in all types of infrastructural applications because it offers considerable strength at a relatively low cost. The popularity of the concrete is due to the fact, that from the common ingredients, it is possible to tailor the properties of concrete to meet the demands of any particular situation. Concrete is an Artificial Stone resulting from hardening of rationally chosen mixture of cement, fine aggregate, coarse aggregate and water. The advances in concrete technology have paved the way to make the best use of locally available materials by judicious mix proportioning to produce concrete satisfying the performance requirements. This concrete is the most widely used construction material in the world, with about two Billion tons of utilization worldwide during each year. Natural Sand available from River beds, pits etc., was readily used as fine aggregate in all types concrete mixes. Due to rapid urbanization, there is a huge demand / requirement of natural sand ( as fine aggregate) for the construction industry, thereby natural resources of sand was getting depleted day by day, have brought pressures to reduce consumption through the use of supplementary materials. The sustainable development in the construction industry involves the use of non- conventional and innovative materials and recycling of waste materials in order to compensate the lack of natural resources and to find alternative ways for conserving the environment. Copper slag (by-product material produced during the process of manufacturing Copper), is one of the waste material which could have a promising future in construction industry as partial substitute of fine aggregate in concrete mixes. Hence an attempt has made to study the Compressive Strength, Split tensile Strength and Flexural Strength of concrete using different proportions of Copper Slag in concrete mixes to finalize the optimum % of mix which can yield better strength properties. The results presented in this thesis, form part of an investigation on the use of Copper slag as partial substitute/ replacement for natural sand as fine aggregate in concrete.
