Cement compositions with 3D graphene carbons

A method of making a mortar including a cement composition, the method including:

• forming a first mixture by mixing a cement blend with water at a water to cement ratio by weight of between approximately 0.3 and 0.5, wherein the cement blend includes:
• ordinary Portland cement;
• a secondary cementitious material (SCM) including one or more of metakaolin, limestone, or gypsum in an amount up to approximately 70% of a replacement level of ordinary Portland cement;
• and
• a superplasticizer in a concentration range of between approximately 0.05% by weight of cement (bwoc) and 2% bwoc;
• and
• mixing a suspension of aggregates of mesoporous carbon nanoparticles (3DG carbons) in water into the first mixture, wherein the 3DG carbons include oxygen containing functional groups disposed on one or more of the surfaces of the 3DG carbons or within the 3DG carbons.
