  • Polymer concrete and method for preparation thereof
    Patent number: 7977424
    Abstract: A soy-based polyol is mixed with an isocyanate and aggregate to produce a soy-based polyurethane having superior mechanical properties. The aggregate composition may be varied to obtain different mechanical properties, as can the amount of resin. The resin may be crosslinked using a low molecular weight polyol, such as glycerine, to also improve structural performance. A catalyst may be added to accelerate curing time without reducing structural performance.
    Type: Grant
    Filed: August 13, 2001
    Date of Patent: July 12, 2011
    Inventors: Zoran Petrovic, Wei Zhang, Ivan Javni, X. Andrew Guo
