  • Publication number: 20160068735
    Abstract: The invention relates to cementitious or grout compositions and drilling fluids including reinforcement fibers and methods relating thereto. The cementitious or grout compositions include dry blend material and reinforcement fibers. Each of the fibers can have one or more of a pre-selected mean length, denier, diameter and aspect ratio to improve dispersion in dry blending the cementitious or grout compositions.

  • Publication number: 20140303288
    Abstract: The present invention relates to a blend of reinforcement fibers for use in a variety of applications. In particular, the blend of reinforcement fibers can be used in cementitious compositions, such as Portland cement concrete and asphalt cement concrete compositions to reduce or preclude voids and/or cracks formed in the cement concrete upon placement. The blend of reinforcement fibers includes a plurality of first fibers and a plurality of different second fibers. The first and second fibers can be different based on coarseness/fineness, melting temperature, denier and specific chemical or material composition.

  • Patent number: 7168232
    Abstract: The present invention provides a synthetic fiber and methods for its use and formation. The present invention may comprise a fiber component that is a twisted bundle comprised of multiple strands of a nonfibrillating monofilament, the degree of twist being greater than about 0.9 turns/inch (about 0.36 turns/cm). The present invention may further comprise another fiber component, discrete from the twisted fiber component, that is fibrillated.

  • Patent number: 6753081
    Abstract: The present invention provides a synthetic fiber blend and methods for its use comprising a first fiber component formed of a homopolymer polypropylene fiber and a second fiber component being a copolymer formed of a polypropylene and a high density polyethylene. The first fiber component is fibrillated and the second fiber component is a twisted bundle comprised of multiple strands of a nonfibrillating monofilament. The synthetic fiber blend imparts improved reinforcement properties to the building materials to which they are added. In particular, the synthetic fiber blend when incorporated into a building material provides reduced permeability, increased fatigue strength, improved toughness, and reduced plastic shrinkage. The unique combination of the twisted second fiber component blended with the first fiber component provides improved mixability and uniform distribution of the synthetic fiber blend in cementitious materials.

  • Patent number: 6164380
    Abstract: The present invention provides a method for cleaning debris from a bore and includes injecting hydrophilic fibers selected from the group consisting of polyolefins, polyesters and nylons, suspended or dispersed in a water based or oil based liquid into the bore and forcing the suspension through the length of the bore, to its open end. In particular, the suspension is directed through sections of the bore holding quantities of debris formed from the drilling operation. The suspension loosens the debris and sweeps substantial quantities of debris from the bore, and acts to suspend the debris in the liquid in static suspension at times when the liquid is not being forced through the bore.

  • Patent number: 6016872
    Abstract: The present invention provides a method for cleaning debris from a well-bore and includes the steps of injecting hydrophilic fibers selected from the group consisting of polyolefins, polyesters and nylons, suspended or dispersed in a water based or oil based liquid into a well-bore and forcing the suspension upwards, through the length of the well-bore, to its open end. In particular, the suspension is directed through sections of the well-bore holding quantities of debris formed from the drilling operation. The suspension loosens the debris and sweeps substantial quantities of debris from the well-bore.
