ABSTRACT:
Aqueous bay mud sludges, such as dredgings, are converted into load supportive masses by partially dewatering the sludge, which contains solid particles of clay, shell and organic matter, to a solids content of about 15 to 50 weight percent and adding thereto, between 5 to 30 percent by weight, based on solids, of a ground granulated blast furnace slag. Upon settling, the mixture will stabilize to provide a sedentary mass.
