Original Abstract

This paper deals with the effect of combining high temperature and fluidised fly ash, not only on the compressive strength of concrete but also on the determination of the dynamic modulus of concrete test bodies. The use of high-temperature fly ash in concrete mixes has become commonplace. However, the demand for this type of active admixture has increased to such an extent that it currently far exceeds supply, especially after selective non-catalytic nitrogen oxide reduction (SNCR) was introduced and the switch to low-temperature combustion units. This lack of supply makes it necessary to look for other alternative solutions to this situation. The partial replacement of high-temperature fly ash with fluidised bed fly ash appears to be a possible solution.

Keywords
