  • Lightweight modular cementitious panel/tile for use in construction
    Patent number: 7770354
    Abstract: A lightweight cementitious panel/tile is provided with increased bending stiffness and less weight than conventional construction panels. The cementitious panel is constructed of a cementitious surface (which may be reinforced with wood fiber or other materials) supported by an integrated stiffener grid on the underside to absorb stresses and loads.
    Type: Grant

  • Lightweight structural concrete provided with various wood properties
    Patent number: 7736431
    Abstract: A lightweight structural concrete with screw-ability and nail-ability similar to wood is composed of non-structural and ultra lightweight aggregate such as expanded perlite of a particular size distribution and amount, entrained air cells of another specific size distribution and amount, and dense cementitious composition of a cement binder, a fine grade structural filler no larger than masonry sand grade, a pozzolan, and optional micro-fibers for reinforcement. This structural concrete matrix is optimized to hold 13 gauge T-nails and bugle head wood screws with thread ranging from 8 to 11 threads per inch and diameter of 0.10? to 0.137?. The resulting concrete will have consistent screw-ability and nail-ability similar that of wood.
