Abstract
This paper presents the study of properties of concrete with ground granulated blast-furnace slag (GGBF slag). The Portland cement type I replaced partially with the GGBF slag and limestone powder was considered.
The results showed that the normal consistency of paste made with Port land cement type I replaced partially with the GGBF slag and limestone powder was smaller than that of Portland cement type I paste. A paste made from Portland cement type I replaced partially with the GGBF slag and limestone powder had delay of setting time when compared with Portland cement type I paste, In addition. the GGBF slag and limestone powder concrete had smaller slump when compared with Portland cement type 1 concrete specimens. While the compressive strength of concrete made from GGBF slag and limestone powder was slightly to be less than that of Portland cement type 1 concrete. It was also found that the drying shrinkage of concrete with GGBF slag and limestone powder was less than that of Portland cement type I concrete specimens. Finally, it was found that concrete specimens made from Portland cement type 1 partially replaced with GGBF slag and limestone powder had superior resistance chloride penetration when compared with Portland cement type 1concrete specimens.
