Binary ConcreteExpansion by means of Copper Slag, Fly Ash, Sugarcane Bagasse Ash, and Rice Husk Ash as partial replacement of Cement

Abstract

With the rapid evolution in creation activity, the accessible sources essential for cement manufacturing are getting fatigued & also, quality construction constituents may have to be procured from long distance, which increases to the cost of construction. Thus, it is necessary to substitute cement in concrete by an alternative material in part, without negotiating the quality of concrete. A present scenario for waste materials such as Copper Slag (CS), Fly Ash (FA), Sugarcane Bagasse Ash (SCBA), and Rice Husk Ash (RHA) is problematic to dispose of which in reoccurrence is an environmental threat so to offer justice with these cementitious materials needs to be investigated. In the present paper, an investigation is carried out on the specific applications of Copper Slag, Fly ash, Sugarcane Bagasse Ash, and Rice Husk Ash on the Compressive strength of Concrete Strength. This paper summarizes the research work on the properties of Copper Slag, Sugarcane Bagasse Ash, and Rice Husk Ash, and Fly Ash when castoff as a partial replacement for Ordinary Portland Cement (OPC-53) in M25 grade concrete. Mix design was prepared as per IS 10262-2009. All necessary lab tests carried out in the laboratory including physical and chemical characteristics of each material. OPC was replaced with ashes and slag by weight at 5,10,15,20,25 and 30%. Workability test was carried out on fresh concrete while the Compressive Strength Test was carried out on mould specimen, 150mmx150mmx150mm concrete cubes after 7, 28, 56 and 90 days curing in water. The results were compared to the conventional sample. strength gain of concrete after 28 days becomes slow when Sugarcane Bagasse Ash, Rice Husk Ash, and Fly Ash are used. Copper slag improved the workability of concrete. Consequently, the use of ashes and slag in concrete lessens environmental pollution, enhances the properties of concrete and also reduces the cost.
