Patent number: 7427321Abstract: Disclosed are formulations adapted to form a foamed cementitious composition, the foamed cementitious composition itself, a method of forming a hydraulic binder foam, and a method of conveying and applying the resulting foam to a substrate. A pumpable cementitious slurry is formed, the slurry is mixed with a gas such as air, and is subjected to mechanically created turbulence to generate gas bubbles and create a foam, which preferably is stabilized by a foam stabilizing agent such as polyvinyl alcohol present in the slurry. The foam is then conveyed to a nozzle or other suitable dispense point from which it is applied, for example sprayed, preferably uniformly, onto a substrate to be coated. Prior to dispensing, a set accelerator is preferably injected, which causes the foam to gel, which in turn improves the hangability of the product on a substrate. The spray material adheres to the substrate and hardens to form an insulative coating on the substrate.Type: GrantFiled: September 30, 2003Date of Patent: September 23, 2008Assignee: W.R. Grace & Co. -Conn.Inventors: Dennis M. Hilton, Michael D. Morgan, Robert Paul, Karl D. Taub, Robert S. Young, Ricky N. Bastarache

Patent number: 5462235Abstract: An apparatus for producing shredded aggregate from, e.g., boards of expanded polystyrene, is described. The apparatus includes a shredding box defining a shredding chamber; a rotor housed in the shredding box; means for driving the rotor; a plurality of saw blades coupled to the rotor in linear succession, each saw blade having a plurality of spaced apart teeth, each successive saw blade being coupled to the rotor such that its teeth lie about halfway between the teeth of an adjacent saw blade; receiving means in the shredder box for receiving material to be shredded; and take-away means coupled to the shredder box for removing shredded material from the shredding chamber. Low density (e.g., 0.4-0.5 pcf loose bulk density) material having a uniform particle size distribution over time can be economically produced.Type: GrantFiled: December 8, 1992Date of Patent: October 31, 1995Assignee: W.
