Assessment of the potential for using EAFD in cement paste in Jordan

Abstract

This paper presents an experimental investigation on the effect of electrical arc furnace dust (EAFD) on normal consistency, setting time, soundness, dry bulk density and compressive strength of hardened cement pastes. EAFD dusts were used to partially replace cement at 0, 1, 3, 5, 10, 15 and 20% by weight. Test results showed that the cement paste with EAFD produced paste with lower normal consistency than original cement paste (0% of EAFD). The rate of decrease in normal consistency is observed to be more for percentage replacement (10–20%). In addition, the result found that EAFD prolonged the setting time of cement paste. The dry bulk density of paste was strongly affected by the replacement of EAFD. EAFD decreased the dry bulk density and therefore increased the porosity.
