Dump area reclamation with the use of bottom sludge suspension

Żelazny S., Fela K., Jarosiński A., Kowalski Z.

Polish Journal of Chemical Technology

2006

Vol. 8, nr 2

48-53

The study on the alkaline sludge from the ,,Górka" settling pond utilization as a component of the quasi-concrete composite was presented in this paper. Solidification with the mineral binding material was chosen as the method. The purpose of this work was to obtain a composite, whose properties would comply with the standards. Therefore, the crushing strength and harmful substances leaching tests were carried out. Having considered their results it can be stated that 15% addition of the binding material (in relation to the dry waste mass) guarantees the material solidification and ensures suitable mechanical and chemical properties of the composite. The obtained composites can be applied to waste dump reclamation or to the quasi-concrete elements production.
