Reaction product of Crude sludge and Calcium oxide. Crude sludge is the mixture of by-products of petroleum hydrocarbons refining (especially Total petroleum hydrocarbons, Polycyclic aromatic hydrocarbons, acid-refined heavy petroleum distillates). The Crude sludge is neutralised by calcium oxide in the ratio 80:20. The maturing process proceeds under ambient conditions and takes for at least 3 days. Subsequently, the reaction product is processed mechanically.

Description of key information
Additional information
Data on physical and chemical properties were obtained from results of laboratory studies performed in accordance with EU or OECD guidelines. The studies were performed in accordance with GLP principles.
For the data of physical and chemical properties, that could not be obtained by experimental studies or could not be estimated by calculation, were elaborated the Expert statements (for example oxidizing properties, partition coefficient).
Other missing physical and chemical data that could not be determined by reasons stated in column 2 of the Annex VII (for example boiling point, surface tension, flash point, dissociation constant, viscosity) were justified.
