Abstract

In this study, the properties of binary mixtures containing phosphorus slag (80 wt.%) and Portland based-chemical activator (20 wt.%) at three Blaine fineness of 2050, 3030, and 4500 cm2/g were studied. Also, Blaine fineness of 3030 cm2/g was selected to investigate the effect of curing temperature of 45, 85, and 200 ºC on compressive strength improvement. The experimental results showed that with enhancement of Blaine fineness, the bulk density and setting time decrease and water-to-cement ratio and compressive strength increase and at temperatures higher than 45 ºC, compressive strength decreases at later curing times.
