I am curious whether this will become an option, especially for longer lasting structures. Could pre-stressed graphene or another high tensile strength material by used to reinforce granite block construction?
Potentially relevant values:
Thermal Expansion Coeffiecients:
granite 7.9−8.4⋅10−6 m/mK,
graphene: it has a negative thermal expansion value
concrete: ~40 MPa
granite: ~200 MPa
Rebar: 420 MPa
Graphene: 130.5 GPa
Please note I am not certain of these values.
