Název v původním jazyce

Stabilization and solidification of hazardous waste by using cementation

Popis výsledku v původním jazyce

Waste from chemical industry represents a big danger for people and the environment. Mainly because of its complicated composition and significant amount of heavy metals. Manipulation of industrial waste has to fully fulfil one basic aim, which is the safety of all liquidation processes. The most common way of disposing of chemical waste in the Czech Republic is to incinerate it. The waste from incinerators, such as ash, slag, fly ash and active carbon, contains dangerous substances. Fly ash is a waste material generated during combustion. It is a heterogeneous material consisting of particles having various properties, both physical, chemical, mineralogical, morphological and technological. It is a suitable material for construction purposes, for their significant pozzolanic properties. Fly ashes are processed by bituminization, vitrification, and cementation. Fly ash sample was subjected to process of stabilization by using cementation. For stabilization process of cementation was used cement, which was successfully used to stabilize of soils. Stabilization of fly ash was assessed applying three different amounts of cement admixture and four distinct solidification periods in order to decrease the amount of leachable harmful elements or compounds the waste. The assessment of the observed parameters was performed according to the EU standard 2003/33/EC for waste acceptable at landfills for hazardous waste. The aim of stabilization of processes were to assess, whether it is a suitable method for treatment of fly ash from incinerators and hazardous waste if it will reduce their danger.
