Verification of the Possibility of Solidification Product Made of Neutralization Sludge use in the Building Industry

Abstract

This paper deals with hazardous waste solidification /stabilisation, specifically neutralization sludge that comes from active industrial sources and neutralization sludge that comes from old ecological sources. As solidification agents fluidized bed combustion ash, classic fly ash and ordinary Portland cement were used. According to the valid legislation and selected possible future use of solidification product a laboratory testing of proposed solidification /stabilisation recipes was performed. The results of leachability tests, unconfined compressive strength and ecotoxicological test showed that solidification product use as a technological and reclamation material on depots and setting pits is possible.This paper deals with hazardous waste solidification /stabilisation, specifically neutralization sludge that comes from active industrial sources and neutralization sludge that comes from old ecological sources.
