US Patent:

44966598, Jan 29, 1985
Filed:

Feb 13, 1984
Appl. No.:

6/579327
Inventors:

Edward L. Nimer - San Rafael CA
Robert W. Campbell - Lafayette CA
Assignee:

Chevron Research Company - San Francisco CA
International Classification:

C04B 1906
US Classification:

501140
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.

US Patent:

43768300, Mar 15, 1983
Filed:

Aug 10, 1981
Appl. No.:

6/291587
Inventors:

Edward L. Nimer - San Rafael CA
Robert W. Campbell - Lafayette CA
Assignee:

Chevron Research Company - San Francisco CA
International Classification:

C04B 3304
US Classification:

501140
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.

Filed:

Feb 23, 1981
Appl. No.:

6/237349
Inventors:

Edward L. Nimer - San Rafael CA
Robert W. Campbell - Lafayette CA
Assignee:

Chevron Research - San Francisco CA
International Classification:

C04B 3304
US Classification:

501140
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.
