Abstract – As the consumption of concrete increases, the world production of cement is continuing and grew to a significant amount. Portland cement production is a highly energy intensive process, and emits CO2 during calcinations which has a crucial effect on global warming. The production of one tone of ordinary Portland cement (OPC) releases approximately one tonne of carbon dioxide to the atmosphere. Scarcity of Natural River sand because of environmental condition . It is necessary to replace natural sand in concrete by an alternate material partially, without compromising the quality of concrete. Adding partial replacement on cement with fly ash and complete replacement of sand with M- sand in concrete is desirable because of benefits such as increased workability, reduction of cement consumption and decreased permeability and useful disposal of a byproduct, reduction of river sand consumption and increased strength respectively. The incorporation of flyash as partial replacement of cement in concrete and is a common practice and along with that the use of nano particles has received particular attention in the application of construction materials especially in cement mortar and concrete.The application of nanomaterials in construction is a new alternative to enhance the mechanical properties of the concretes. One of the most interesting nanomaterials which still requires detailed investigation is graphene and graphene oxide. The study presented in this paper aims at assessing how 0.03 to 0.11 wt% of graphene oxide incorporated into the cement can affect the physical–mechanical properties of the cement composite in fly ash concrete.
