Billy D. Neeley has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Structures and components comprising blast-resistant concrete also suitable for limiting penetration of ballistic fragments
    Patent number: 8016938
    Abstract: Concrete structures and components with improved strength and toughness. A uniform mix of first constituents comprises: cement of Blaine fineness of 280-360 m2/kg; sand at a mass ratio of 0.75-1.25 of the cement; silica fume at a mass ratio of 0.15-0.4 of the cement; silica flour at a mass ratio of 0.15-0.3 of the cement; and microinclusions at a mass ratio up to 0.35 of the cement. This is then mixed with a blend of second constituents comprising a specified amount of an HRWRA and an amount of water at a mass ratio of 0.2-0.35 of the cement. This is mixed sufficiently to form a uniform cement-based paste to which an amount of macrofibers at a mass ratio of up to 0.35 of the cement is added to yield a uniform product. Nanoinclusions may be added to improve crack resistance and increase density.
    Type: Grant
    Filed: May 7, 2010
    Date of Patent: September 13, 2011
    Assignee: The United States of America as represented by the Secretary of the Army
