Researching the effect of Graphene Oxide on the properties of Ultra-high Performance Concrete

Abstract

Ultra-high Performance Concrete is made from a mixture of components using a very large cement content (700÷1100 kg/m3), so UHPC has a very large shrinkage, then the production of products Large size will easily appear rift surface. Although, this shortcoming has been partially overcome by dispersed fiber reinforcement, but the core thing is still to minimize the amount of cement used. In addition to replacing part of cement with finely ground blast furnace slag, Graphene Oxide (GO) can also be used because it is nano-sized, very well dispersed and directly affects the mechanical properties. chemistry of cementitious materials (UHPC).

Keywords: Ultra-high performance concrete; Graphene Oxide; flows; compressive strength; tensile strength; curing.
