Title: UPDATE ON SULFATE-INDUCED HEAVE IN TREATED CLAYS; PROBLEMATIC SULFATE LEVELS
Accession Number: 00625709
Record Type: Component
Availability: Find a library where document is available Abstract: A brief background on sulfate-induced heave in lime- and portland cement-treated clay soils and some examples of projects affected by this phenomenon are presented. The nature and details of the phenomenon are covered as known at this time. A type of swell test that may be used to indicate the nature of problems is introduced, as well as some results from known affected sulfate-bearing soils. The main thrust of discussion is the determination of soluble sulfates and how varied the results of such testing can be depending on the procedure used to extract sulfate from the soil. Recommended procedures for extraction and determination of sulfates are provided. Levels of sulfates that represent potential problems are discussed. The conclusions include the minerals that need to be controlled, recommended determination of sulfate levels, recommended testing for problematic behavior, recommended problematic sulfate levels, and recommended research to achieve solutions to the problem.
