Abstract
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.
Claims22
A method of forming a thermodynamically stable cement material comprising:
- mixing a curing agent with a calcium aluminate cement (CAC);
- and
- curing the CAC at one or more curing temperatures through one or more thermodynamically stable phases to form the thermodynamically stable cement material.
A thermodynamically stable cement material comprising:
- a curing agent comprising a hydrophilic material;
- and
- a calcium aluminate cement (CAC).
