(57) Cement compositions including ordinary Portland cement, a supplementary cementitious material (SCM) including one or more of, metalcaolin, limestone, or gypsum in an amount of up to approximately 70% of a replacement level of ordinary Portland cement, and between approximately 0.05% by weight of cement (bwoc) and 2% bwoc of a carbon-based material including three-dimensional graphene flakes (3DG) carbons. Concrete compositions including the cement compositions with 3DG carbons. The 3DG carbons include aggregates of mesoporous carbon nanoparticles, which include one or more interconnected bundles of electrically conductive graphene layers. The 3DG carbons include oxygen containing functional groups or nano-silica particles disposed on one or more of the surfaces of the 3DG carbons or within the 3DG carbons.
