  • Sulfur cement-aggregate compositions and methods for preparing
    Patent number: 4496659
    Abstract: Sulfur cement-aggregate compositions comprising a sulfur cement and an aggregate containing an expansive clay and processes for preparing such compositions. The processes, and resulting compositions, are characterized by the incorporation of a carboxylic acid therein. The resulting solidified composition has improved water stability.The compositions can be used as mortars or concretes depending on the particle size of the principal aggregate component.
    Type: Grant
    Filed: February 13, 1984
    Date of Patent: January 29, 1985
    Assignee: Chevron Research Company
    Inventors: Edward L. Nimer, Robert W. Campbell
  • Sulfur cement-aggregate-organosilane compositions and methods for preparing
    Patent number: 4376830
    Abstract: Sulfur cement-aggregate compositions comprising a sulfur cement and an aggregate containing an expansive clay and processes for preparing such compositions. The processes, and resulting compositions, are characterized by the addition of certain organosilanes in the composition prior to solidifying (cooling) the composition. The resulting solidified composition has improved water stability.The compositions can be used as mortars or concretes depending on the particle size of the principal aggregate component.
    Type: Grant
    Filed: August 10, 1981
    Date of Patent: March 15, 1983
    Assignee: Chevron Research Company
    Inventors: Edward L. Nimer, Robert W. Campbell
  • Sulfur cement-aggregate compositions and methods for preparing
    Patent number: 4332911
    Abstract: Sulfur cement-aggregate compositions comprising a sulfur cement and an aggregate containing an expansive clay and processes for preparing such adhesives. The processes, and resulting compositions, are characterized by adding a water soluble salt to the aggregate and then admixing said aggregate-salt mixture with molten sulfur cement. The resulting solidified composition has improved water stability.The compositions can be used as mortars or concretes depending on the particle sizes of the principal aggregate component.
