Impact of fine aggregates replacement by fluidized fly ash to resistance of concretes to aggressive media

Jiri Brozovsky, Tomas Fojtik, Petr Martinec

Abstract


Fluidized fly ashes constitute a part of industrial waste used in building material production on a small scale up to now. Concrete production is one of fluidized fly ashes application field. This paper presents findings concerning testing of concrete with addition of fluid combustion ashes as to aggressive media resistance - chlorides and sulphates in particular. Fine grained aggregate has been replaced by deposit ash (0 to 50 %). This ash originates from black coal fluid combustion in the TZ Trinec Power Plant. Concrete samples have been exposed for a period of 24 months.
