PROPERTIES OF HIGH TEMPERATURE FLY ASHES AFTER APPLICATION SNCR TECHNOLOGY FROM THE CONCRETE PRODUCERS POINT OF VIEW

Popis výsledku v původním jazyce

This paper deals with the current issue of the usability of high-temperature power fly ash after the process of denitrification of flue gas through selective non-catalytic reduction of nitrogen oxides (SNCR). With the onset of new European legislation, nitrogen oxide emissions were severely reduced, which resulted in almost all power fly ash producers within the Czech Republic and neighbouring countries being introduced to the SNCR ncineration process. The impact of the SNCR mechanism on the usability of fly ash for the production of concrete is the topic of many current research papers, which attempt to clarify the impact of SNCR on the properties of fly ash or the concrete produced from it. This paper summarises present knowledge and gives an overview of the production of concrete with this type of fly ash in the real conditions of the plant. It further measures and assesses its impact on air contamination by ammonia and groundwater contamination caused by concrete leachates with respect to safety limits. In addition, the results are supplemented by tests carried out in accordance with the EN 450-1 standard for fly ash used in concrete production.
