Abstract

Typical polluted maintenance dredgings from several different harbors are investigated to determine the amount of organic matter present and the effect of this organic matter on various engineering properties, such as compresibility, permeability, strength, and density; in addition, the results of supporting mineralogical and chemical analyses, as well as gradation and limit tests, are reported. Both dry combustion and wet combustion testing procedures are used to make the organic content determinations, and the results are found to be highly dependent on the type of test and the suitability of a particular test for a given material. The liquid limit, plastic limit, and plasticity index generally increase with increasing values of organic content, but there is considerable scatter in the data. Refs.
