    摘要: The present disclosure relates to cementitious fluids comprising additives configured to form a permeable cement matrix after curing of the cement. The cementitious fluids can comprise a cementitious medium (e.g., a cement slurry) with a plurality of fibers dispersed therein. The fibers can be hollow, can be porous, and can be degradable. The cementitious fluid particularly can be used in methods of stimulating hydrocarbon bearing formations. Specifically, the cementitious fluid can be injected into the formation to form or enlarge a fracture, and the fluid can be cured to form the permeable cement matrix, said permeability arising from a loosely assembled tubular network and/or passages remaining after degradation of the fibers.

    摘要: Disclosed are polymeric additives for concrete formed of a polyoxymethylene (POM) copolymer. POM copolymers can be utilized to form fibrous additives for concrete, i.e., microfibers and/or macrofibers. The POM copolymers can include one or more chemical groups, e.g., end groups and/or pendant groups that can increase the polarity of the POM and increase the hydrophilicity of the formed fibers, which can improve miscibility of the fibers in wet concrete. Chemical groups of the POM copolymers can bond with components of the concrete or can hydrolyze to form groups that can bond with components of the concrete, e.g., form covalent or noncovalent (e.g., electrostatic or ionic) bonds with one or more components of the concrete binder.
