An Experimental Study On Concrete Using Fly-Ash, Copper Slag and GGBFS

Concrete Technology

The replacement of natural resources in the manufacture of cement and sand is the present issue in the present construction scenario. Fly-Ash, Copper slag and Ground Granulated Blast Furnace Slag (GGBFS) are industrial by-product materials produced from the process of manufacturing coal, copper and iron. Use of Fly-Ash, Copper slag and GGBS does not only reduce the cost of construction but also helps to reduce the impact on environment by consuming the material generally considered as waste product. current study with minimize the cost of cement and sand with concrete mix grade M20 by studying the mechanical behavior of this concrete mix by partial replacing with such as Fly-Ash, Copper slag and GGBS in concrete mix. In this study, partial replacement of Cement with Fly-Ash and Sand with Copper Slag and coarse aggregate with GGBFS considered. Experimental study is conducted to evaluate the workability and strength characteristics of hardened concrete, properties of concrete have been assessed by partially replacing cement with GGBS, and sand with Copper Slag. The cement has been replaced by Fly-Ash accordingly 10% and sand has been replaced by Copper slag accordingly 30% based on past research paper. Corse aggregate has been replaced by GGBFS accordingly (without Fly-Ash and Copper slag), 20%, 40%, 60%, 80% and 100% for M20 mix. Concrete mixtures were produced, tested and compared in terms of compressive, flexural and split tensile strength with the conventional concrete.
