RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:Supply agreements are legally binding!Here is what first graphene said in their annual report. "Initial studies at the University of Adelaide showed compressive strength is increased by 34.3% and tensile strength by 26.9% when PureGRAPH is added to cement mortar at very low levels of 0.07%w/w in the cement paste (equivalent to ca. 0.01%w/w in concrete)" so the loading portions does no seem to be as high as you think. did i mention that Gerdau signed a non binding MoU with first graphene and a supply & distribution contract with NanoXplore...
