Abstract

The use of
wastes has become very significant and widespread in terms of sustainable production
of clayey mixtures, since the wastes provide many advantages. In this study, the
effects of two different types of fly ash, which were wastes of Seyitomer and
Cayirhan thermal power plants,    on the
color change of brick samples with various amount of fly ash ranging between 0
to 60% at different sintering temperatures were investigated. As a result,
traditional red colored bricks could be produced with fly ash without using a
separate raw material to meet the color requirements. It was found that desired
colors for special architectural applications could also be achieved by using
fly ash.

Keywords
