CEMENT COMPOSITIONS WITH 3D GRAPHENE CARBONS
Cement compositions including ordinary Portland cement, a secondary cementitious material (SCM) including one or more of pozzolan, metakaolin, limestone, or gypsum in an amount corresponding to at least approximately 70% replacement level of ordinary Portland cement, and between about 0.05% bwoc and 2% bwoc of aggregates of 3-dimensional graphene (3DG) carbons. The cement compositions regulate nucleation and time-lapsed growth of calcium silica hydrates during initial hydration. The 3DG carbons include one or more of graphene nanoplatelets orthogonally joined to each other to form a 3D porous graphene scaffold structure. The 3DG carbons may also include a plurality of aggregates of carbon nanoparticles characterized by a plurality of porous concentric shells including graphene, where each shell encloses a porous carbon region and an interconnected porous network disposed in each carbon region and in fluid communication with contiguous carbon regions.
