Influence of Graphene Oxide on Compressive Strength of Cement Paste

It is shown that graphene oxide is perspective material for improvement of physical and mechanical properties of cement composites. Data of foreign researches demonstrate that graphene oxide provides substantial increase of durability of cement composites on compression and on a bend both in early and in design terms of curing. At present many articles have appeared devoted to clarification of probabilistic mechanism of durability increase of cement composites at nanoadditive introduction of graphene oxide. However the mechanism of increase in durability isn’t found out yet, there are different opinions, sometimes contradictory. Results of pilot studies of graphene oxide influence on strength properties of cement stone are given. Use of high-speed mixer at preparation of samples allowed to receive substantial increase of durability. For graphene oxide distribution studying in a cement stone the method of scanning electronic microscopy on JEOL F7500 is used.
