  • Patent number: 6083318
    Abstract: A lightweight, cementitious composition and method which includes a noncementitious filler, Portland cement, bentonite, diataomaceous earth and lime. The noncementitious filler may be sawdust, rubber chips, flyash or combinations of two or more of these ingredients. Once mixed with water and air, the composition can be molded to form a variety of structures, including electrically nonconductive posts, and can be used to absorb and contain liquid contaminants in a vessel.
    Type: Grant
    Filed: December 21, 1998
    Date of Patent: July 4, 2000
    Inventors: Joseph M. Zawada, Sandra K. Zawada

  • Patent number: 5782970
    Abstract: A lightweight insulating concrete is produced from a cement mix containing sawdust, diatomite, bentonite, and lime. The addition of rock salt and the entrainment of air bubbles results in a concrete with a high compressive strength, high thermal resistance (R) values (up to 30 to 40 times that of standard concrete), and excellent acoustical properties. The new insulating concrete is one third the weight of standard concrete. The composition is fire retardant, insect proof, and is very easy to clean up. Methods for producing cementitious materials include a process for manufacturing strong, lightweight, waterproof building products such as wall panels and roof panels. The mixture can be easily pumped for walls and floors. A well-insulated, cost-effective floor that has a slight give to it is excellent for gymnasium floors. This material is used for residential, light commercial, and agricultural buildings.
