Öğütülmüş Yüksek Fırın Cürufu, Uçucu Kül ve Silika Dumanı İçeren Harçların Yüksek Sıcaklık Direnci

Abstract

In the current study, elevated heat resistance of the mortars including 15% fly ash, ground granulated blast furnace slag and silica fume is investigated. Fly ash, ground granulated blast furnace slag and silica fume are replaced with cement past by weight in the prepared mortar samples. The prepared samples are kept in a furnace for 2 hours at 400 °C and 800 °C to find out effect of elevated temperature on compressive strength of the mortars. Compressive strength before and after heat exposure are measured in terms of evaluating elevated heat resistance. Control sample that does not contain any admixture, mortar including fly ash, mortar including ground granulated blast furnace slag and mortar including silica fume has 30.
