  • Utilization of heavy oil fly ash to improve asphalt binder and asphalt concrete performance
    Patent number: 8444761
    Abstract: Disclosed herein are an asphalt concrete mixture, an asphalt binder composition, and methods of preparing the related compositions. The asphalt binder compositions include heavy oil fly ash that contains more than about 90 wt. % carbon. The compositions are capable of being performance graded. The binder can be used to modify the asphalt and also as a filler in asphaltic concrete compositions.

  • PROTECTION SYSTEM FOR SULFUR STORAGE APPARATUS
    Publication number: 20120211391
    Abstract: A calcium alumninate cement protective coating is resistant to sulfuric acid and can be used as a lining to protect surfaces in sulfur storage vessels and sulfuric acid storage vessels. The protective coating can include calcium aluminate cement, calcium aluminate based synthetic aggregates, and water. The protective coating is resistant to sulfur and sulfuric acid attack, and thus can be used to protect surfaces inside sulfur storage pits, sulfur storage tanks, and sulfuric acid storage containers.

  • Economical Heavy Concrete Weight Coating for Submarine Pipelines
    Publication number: 20110283516
    Abstract: Economical heavy concrete weight coating is used as a weight coating for submarine pipes. The developed economical heavy concrete weight includes steel slag and iron ore as aggregate. Steel slag can contain iron and thus have a higher density than some other types of slag. By supplementing the steel slag with iron ore as aggregate, the economical heavy concrete weight coating can have a higher density than a coating having just slag. Economical heavy concrete weight coating can have a density greater than 190 pcf.
