Abstract
A cementitious nano-engineered method and resultant composite includes a modified aggregate material configured from a plurality of fine aggregate particles (FAg) particles pretreated with a graphene oxide (GO), wherein the graphene oxide (GO) is further arranged as a plurality of crosslinked structures that arranges for a refined interfacial zone (ITZ) with a thickness of 3 μm to 10 μm; and a water/cement (w/c) ratio content configured with the modified aggregate material. The interface of modified aggregate and a cementitious phase largely determines the mechanical properties and durability performances of cement mortar and concrete. Moreover, the methods and composites also provide for a targeted and more efficient approach to develop smart cement composites through nanoengineering of the interfacial transition zone.
