Hydraulic road binder with high share of fly ash after denitrification

Popis výsledku v původním jazyce

Power plants use new technologies to reduce emissions limits. Denitrification is a process that leads to the reduction of nitrogen oxides (NOx) in the flue gas. However, in this process, the ammonia or urea is bound to the fly ash and it may adversely affect the properties of this secondary material and it influences its practical utilisation. In this contribution research of siliceous fly ash after denitrification by SNCR in the field of hydraulic road binders for soil treatment is described. In the last time a number of new hydraulic road binders with fly ash as their component have been prepared and used. Fly ash is used due to its pozzolan properties (siliceous FA) or hydraulic properties (calcareous FA) and low purchase price. In described case, fly ash after denitrification was used in mixture with Portland cement and cement kiln dust in ratio 60/30/10. The prepared mixture showed satisfactory properties to meet the requirements of the EN 13282-2: Normal hardening hydraulic road binders. These binders have to comply with the requirements determined by cement standards.
