  • Publication number: 20120298012
    Abstract: Portland Cement-based concretes and mortars exhibit significant reduction in shrinkage cracking when combined with Magnesium Oxide (MgO), Shrinkage Reduction Admixtures (SRA) and Super Absorbent Polymers (SAP). However, MgO is a solid that reacts with water, SRA is a liquid, and SAP if not added properly could pull water out of the system and thus increase shrinkage. Unique admixture blends used as supplementary cementing materials that do not significantly affect concrete or cement strength properties of Portland cement itself address such issues. Proper ratios of MgO, SRA and/or SAP perform better against crack reduction when compared to commonly used Expansive Cements (EC).

  • Publication number: 20120071591
    Abstract: The present invention relates to plastic materials comprising lignin and poly (butylene succinate) (PBS) to methods of manufacturing those plastic materials and to articles obtained by molding the plastic materials of the invention. Since PBS can be obtained from renewable sources, the present invention also provides for bioplastic materials comprising lignin and PBS. The present invention also provides for plastic materials comprising lignin and PBS and at least one fiber and to articles obtained from those plastic materials that are degradable, compostable and recyclable.

  • Publication number: 20120064061
    Abstract: Provided is an adhesive composition disclosed herein includes tannin, poly(ethylene glycol) and water. The adhesive composition has little toxicity, allows adhesion even in the absence of a thermosetting curing agent, and is hardly soluble in water to show moisture resistance, unlike known tannin adhesives. Therefore, the adhesive composition may be used as a medical adhesive, adhesive depot for sustained release of drug, anti-adhesion agent, cell/protein adsorption barrier and medical hemostatic applicable to various wet environments.

  • Publication number: 20120003471
    Abstract: The invention relates to a process for preparing a composition comprising 10 to 45% of the total solids weight lignin, polyacrylonitrile or a polyacrylonitrile copolymer, and a solvent to form a lignin-based polyacrylonitrile-containing dope and the resulting products. The dope can be processed to produce fibers, including precursor, oxidized and carbonized fibers. The oxidized fibers are of value for their flame resistant properties and carbonized fibers are suitable for use in applications requiring high strength fibers, or to be used to form composite materials.
