Abstract

1536596 Soil stabilisation DRAVO CORP 22 July 1976 [22 July 1975] 30577/76 Divided out of 1429905 Heading E1F [Also in Division C1] An aqueous coal processing waste sludge is converted into a mass of improved load supportine properties by adding to the sludge which has a solids content of 20-80% by weight from 2 to 50% by weight of granulated blast furnace slag and mixing. Lime may be added to the sludge to adjust pH.
