  • Patent number: 9963638
    Abstract: Techniques and methods are disclosed for facilitating the fireproofing application process to the structural members of buildings (e.g., houses, apartment buildings, office buildings, sky-rises, etc.) and for improving the structural integrity of steel when exposed to extreme temperatures. The components of the Universal Fireproofing Patch provide a fireproofing protection product that exceeds Underwriters Laboratories fireproofing guidelines, which may be used under any circumstances (i.e., in the event the existing material to be fire-patched is either unknown or unavailable). The components of the Universal Fireproofing Patch enable a user the ability to coat a non-conforming area quickly, easily and for a fraction of the price compared to commercial patching services. Finally, the Universal Fireproofing Patch is sold as a kit that is comprised of a container, a premeasured quantity of water and fireproofing mix, a mixer, a trowel and an instrument capable of measuring liquids.

    Abstract: A process of manufacturing cement clinker is provided in which a clean supply of CO2 gas may be captured. The process also involves using an open loop conversion of CaO/MgO from a calciner to capture CO2 from combustion flue gases thereby forming CaCO3/CaMg(CO3)2. The CaCO3/CaMg(CO3)2 is then returned to the calciner where CO2 gas is evolved. The evolved CO2 gas, along with other evolved CO2 gases from the calciner are removed from the calciner. The reactants (CaO/MgO) are feed to a high temperature calciner for control of the clinker production composition.

  • Patent number: 7712530
    Abstract: A pre-stressed annular sealant and method of creating a durable seal in a well bore annulus which is based on hydraulic cement that is designed to be easily pumped and placed into a casing-wellbore annulus, to set into a hardened mass, and to then undergo post-set crystal growth and phase changes in the crystalline matrix to combat inherent volumetric shrinkage and to create internally-generated compressive stress in the cement matrix. This internally-generated compressive pre-stressing compensates for tensile stress induced by well operations. The tensile stress must be greater in magnitude than the magnitude of the compressive pre-stress plus the magnitude of the cement's tensile strength before the cement sheath will fail in tension. This expansion and pre-stressing also creates significantly higher shear bond strengths than those developed with ordinary hydraulic cement.

The aqueous component includes water and a hydrophobic adsorbent or absorbent. The hydrophobic adsorbent or absorbent is included in the aqueous component to avoid the emergence of the paste-forming agent, which is at the very least unsightly, when the aqueous component is mixed with the bonding agent component. The hydrophobic adsorbent or absorbent binds the paste-forming agent which would otherwise escape during mixing and remains as an inert additive in the setting mortar composition, without reducing the hardness thereof.
