A Study on Graphene with Cement Concrete

Abstract

One of the materials that is most often recognized is concrete. Concrete is superior to other building materials because of its high compressive strength as well as other benefits like water resistance, low maintenance costs, ease of moulding to the necessary size and form, low manufacturing energy consumption, and so on. Tensile reinforcement of some kind is therefore necessary for concrete. In this study, graphene is added to concrete of grade M30 to increase its split tensile strength, compressive strength, and resistance to cracking when exposed to tensile stress. "High Shear Exfoliation" is the term for the procedure whereby graphene and water are mixed. There is a noticeable difference between graphene and concrete. Rebarred concrete with graphene also reduces the "Alkali-Silica Reaction." The goal of this research is to use cement composites to study graphene and its derivatives. The silicon oxide functional groups in the graphene employed in this work were polymerized and rendered inactive for chemical interaction with the cement hydrates. Another use for graphene is as an anti-corrosion covering. We are testing different percentages of graphene—0.5%, 1.0%, 1.5%, and 2.0% by weight of cement—on concrete specimens, cubes measuring 150 x 150 x 150 mm and beams measuring 500 x 100 x 100 mm. The outcomes were compared to those of regular cement concrete. Specimens of concrete were examined for mechanical characteristics at 7, 14, and 28 days after addition of varying percentages of graphene. The "Optimum Strength of Concrete" was the outcome.
