Field Techniques for Sealing Leaky Concrete Pipe-Lines with Ammoniated Irrigation Waters Open and Closed Conduit Systems Research Program

摘要

The report describes a method for sealing narrow cracks in concrete pipelines by the addition of anhydrous ammonia and other amendments to irrigation waters. Ammonia will produce a hard calcium carbonate precipitate in a water having the proper physiochemical characteristics. The precipitate then deposits in the cracks in the pipe and seals the leaks.
