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.
