An Experimental Study On the Strength Properties of Graphene Oxide Concrete with Partial Replacement of Coarse Aggregate by Recycled Coarse Aggregate

Abstract

In order to reduce the construction waste in the civilizing world, we need to think for alternative cost effective and relatively easier technological methods to reduce construction waste. It is seen that 60%-67% of coarse aggregate are present in the concrete demolished waste. Concrete waste is broken into pieces and used as recycled coarse aggregate. As the world’s population increases the natural resources get depleting. The concern with need of raw materials and production of large amount of waste has led to several studies and solution for this problem is use of recycled aggregate in concrete. Use of recycled aggregates reduce the need of landfill and Cost. The preliminary tests such as water absorption, specific gravity and crushing strength are conducted for recycled aggregate and compared with natural aggregate. Graphene oxide is an allotrope of carbon. From past studies using graphene oxide, there is an appreciable increase in compressive, flexural and split tensile strength of concrete. An attempt has been made to study the strength properties by graphene oxide in varying percentage 0%, 0.05%, 0.1%.0.15% and 0.2% of cement and replacing partially natural aggregate by recycled aggregate in 0, 10, 20 and 30 percent.
