Cement compositions including ordinary Portland cement, a secondary cementitious material (SCM) including one or more of pozzolan, metakaolin, 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 aggregates of mesoporous carbon nanoparticles (3DG) carbons. The cement compositions regulate nucleation and time-lapsed growth of calcium silica hydrates during initial hydration. 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 disposed on one or more of the surfaces of the 3DG carbons or within the 3DG carbons.

Disclosed herein are compositions and methods for increasing the viscosity of a calcium-containing fluid by addition of a modifying agent. The resulting enhanced viscosity fluid may be used in a variety of applications including drilling, to create an enhanced-viscosity fluid, and demolition/mining to create an expansive putty for use in underwater and overhead applications.
