A tile backer board has 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide, 14 wt % of 18 wt % of a magnesium chloride dissolved in water; 0.1 wt % to 10 wt % of a stabilizing material with a phosphorus-containing compound, reacting into an amorphous phase cementitious material. The phosphorus-containing compound is a phosphorous acid (A) or a phosphoric acid (B). 0.1 wt % to 30 wt % of an aggregate is added and then a reinforcing component is mixed in or the cement is poured onto the reinforcing component forming a tile backer board.

A process to make a tile backer board includes using a stabilizing material with a phosphorus-containing compound, reacting magnesium containing starting materials into an amorphous phase cementitious material, and adding 0.1 wt % to 30 wt % of an aggregate and a reinforcing component by mixing in or pouring over the reinforcing component and allowing the amorphous phase cementitious material to cure into a tile backer board.

A process to make a cementitious material includes blending 29 wt % to 40 wt % of a magnesium oxide dry powder containing 80 wt % to 98 wt % of magnesium oxide based on a final total weight of the cementitious material with 14 wt % to 18 wt % of a magnesium chloride dissolved in water and reacting to form a liquid suspension, mixing from 2 to 10 minutes, adding a phosphorus-containing material, and allowing the liquid suspension to react into an amorphous phase cementitious material. A portion of the amorphous phase cementitious material grows a plurality of crystals. The plurality of crystals is encapsulated by the amorphous phase cementitious material forming a nano-molecular veneer.

Cement slurry compositions comprising water, an inorganic cement and additive comprising nanocrystalline cellulose, microcrystalline cellulose, cellulose fibrils, or bacterial nanocellulose or combinations thereof have reduced fluid loss values. Such compositions may be prepared and placed in subterranean wells. The compositions are suitable for use during primary cementing or remedial cementing operations.

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.
