TREATED CEMENT MATERIALS AND METHODS
Disclosed herein are thermodynamically stable cement systems comprising a curing agent mixed with a CAC. The curing agent can be hydrophilic to attract bound water. In such a manner, the addition of the curing agent can treat the CAC. The treated material can then be cured to form a thermodynamically stable cement material. The curing agent can comprise a natural fiber material that comprises cellulose. Alternatively, or in addition, the curing agent can comprise cellulose nanoparticles, such as cellulose nanofibrils (CNFs) or cellulose nanocrystals (CNCs). Also disclosed herein are methods of making the same.

Desert sand and filamentous cellulose in concrete and mortar
The present provides a concrete and mortar mix and composition thereof with poor quality sand such as desert sand, hydraulic binder (cement) and filamentous cellulose, where the desert sand/spherical sand replaces conventional concrete river sands. The present disclosure also relates a filamentous cellulose, such as, cellulose filaments (CF), cellulose nano filaments, cellulose nanofibrils (CNF) and microfibrillated cellulose (MFC) as a concrete/mortar and sand adhesion additive with hydraulic binder (cement), and to a method of making the concrete. This method also relates to a method to prevent the sliding of individual sand grains against one another and therefor similarly contributes to the stabilization of the building materials.

HIGH SURFACE AREA INDUCERS FOR CEMENTITIOUS AGGREGATES PRODUCTION
Method and composition for producing aggregates from cement and concrete, including residual or returned concrete. Exemplary methods involve the use of an aggregate-forming inducer that provides a surface anchoring site for cement paste to bond/adhere, such as shredded news print, cardboard, or mixtures thereof, and also including fiber materials such as polymers, glass, and other material fibers. The aggregate-forming inducer is mixed with fresh concrete until aggregates are formed.
