CEMENTITIOUS COMPOSITIONS COMPRISING RECYCLED SUPERABSORBENT POLYMER
A cementitious composition including recycled superabsorbent polymer (RSAP) and a cementitious material. The RSAP has a purity level of at least 85 percent by weight of the RSAP. Also provided is a cementitious composition where the RSAP has substantially low levels of one or more residual drug entities. Also provided is a method for the construction of a self-sealing cement sheath, the method comprising: supplying a self-sealing slurry of a cementitious composition including cementitious material, an aqueous fluid, and RSAP into an underground geological formation, and allowing the self-sealing slurry of the cementitious composition to cure, thereby forming the self-sealing cement sheath. The RSAP is capable of swelling in the presence of fluid to seal any cracks formed in the self-sealing slurry during curing.
