A composite cementitious feedstock comprises discrete elements. Each discrete element includes mineral rock agglutinates having irregular surface regions and cavities. Super absorbent polymer (SAP) particles and cement particles are disposed on the irregular surface regions and in the cavities. A binder coheres the agglutinates, SAP particles, and cement particles.

A composite cementitious feedstock includes mineral rock agglutinates, super absorbent polymer (SAP) particles, cement particles, and a binder. Each of the agglutinates has irregular surface regions and cavities originating at the irregular surface regions. At least a portion of the SAP particles and cement particles are disposed on the irregular surface regions and in the cavities. The binder coheres the agglutinates, SAP particles, and cement particles.

Methods of forming composite block briquettes of prefabricated thinsets, grouts, and self-leveling underlayment products having high sand content, and the resultant composite block briquettes. Processing conditions within a compacting tool are controlled to generate a press force that is applied to a prefabricated cementitious product having a high sand content, whereby the press force enables formation of sustainable prefabricated product briquettes having a high sand content. The controlled compacting processing conditions and parameters of the invention generate usable briquettes that break up and form the intended resultant product of the starting prefabricated cementitious product.

A degradable composite composition including polyglycolic acid and a boron-containing accelerator, and methods of using the same (for example, as a constituent of a treatment fluid of a subterranean formation) are described. The degradable composite composition may be a composition that degrades in environments typically encountered downhole, such as oilfield environments/conditions and/or fluids.
