Investigation on Possible use of Industrial Waste as Partial Replacement of Cement in Concrete
摘要
Concrete is a common traditional material used by the construction industry. Depending on the demand, concrete grades like M10, M20, M30, M40, M50, M60, and M70 were commonly used in building construction. Concrete of a higher grade requires cement with good quality characteristics. Cement production generates a significant quantity of carbon emissions. By replacing some of the virgin cement with pozzolanic materials or industrial wastes, it is possible to reduce CO2 emissions. A variety of industrial wastes, including tannery waste, paper pulp, and electroplating waste, were utilized in the current experiment. An analysis of the waste materials is carried out for determining its fundamental qualities. M20 concrete grade was used for the present study and concrete cubes with standard dimensions of 150 × 150 × 150 mm were made using cement, and cubes were also made using the industrial waste as partial replacement for cement. The cubes were evaluated on 7, 14, and 28th days for its compressive strength and tensile strength. The outcome of the study reflects electroplating sludge (also known as chrome waste) had a higher compressive strength and tensile strength when compared to paper pulp and tannery waste.
