  • Patent number: 10557075
    Abstract: A method of cementing a subterranean formation includes forming a cement composition comprising cementitious material, an aqueous base fluid, a nano-reinforcement particle suspension comprising a surfactant and nano-reinforcement particles such as single-wall carbon nanotubes or multi-wall carbon nanotubes; and pozzolanic material; introducing the cement composition into a subterranean formation; and allowing the cement composition to set in the subterranean formation. A method of making a cement composition includes combining cementitious material, an aqueous base fluid, a nano-reinforcement particle suspension comprising a surfactant, and a pozzolanic material, where the rate of hydration of the surfaces of the cementitious material is less retarded by the surfactant than an equivalent cement composition without pozzolanic material.

    Abstract: The invention provides a process for the production of a cementious material. The process comprises mixing cement starting materials and a particulate healing agent to provide the cementious material. The healing agent comprises coated particles, wherein the coated particles comprise bacterial material and additive. The bacterial material is selected from the group consisting of a bacterium, a lyophilized bacterium and a bacterial spore of a bacterium. The present invention solves these problems, as (substantially leakage-proof) tablets containing the actual healing agent may neither interfere with either the workability of the liquid mixture (“cementious material”) nor negatively affect properties of either mixture or final material (hardened concrete), even when applied in large quantities. During crack formation in cementious based constructions, the particles also crack, and healing agent is released.

  • Patent number: 8246733
    Abstract: The present disclosure describes various building materials used in the building and construction industry, and to buildings or objects constructed therefrom, and to methods of making these building materials. The building materials comprise a polymeric material, such as sodium alginate and/or calcium alginate which confers significant flame-, fire- and heat-resistance or imperviousness to the materials. Other substances can be added to the materials to improve cross-linking and/or to produce resistance to fungal degradation. The building materials which can be produced, processed, or treated using the alginate polymers of the invention include, but are not limited to, wood products; masonry products; wall, roofing, flooring and siding products; and paint products. Further, sodium alginate in the form of a gel may be used as a firebreak to effectively stop the advance of grass fires, wildfires, and forest fires.

  • Publication number: 20110237531
    Abstract: The present invention provides a low-cost, efficient method for producing a glycolipid biosurfactant, in particular, lactonic sophorose lipids. This method is characterized by culturing a microorganism capable of producing the biosurfactant under limited oxygen supply. The present invention enables preferential production of lactonic sophorose lipids and facilitates recovery of the lactonic sophorose lipids in a solid form. Further, the present invention enables production of high purity acidic sophorose lipids by hydrolyzing high purity lactonic sophorose lipids produced by the above method. The present invention also provides lactonic sophorose lipids that possess strong antibacterial and antifungal activities, and an antibacterial and/or antifungal agent containing the sophorose lipids.
