Abstract:
The residuals from industrial will be used beneficially, especially in concrete, resulting in reduction of environment problem. For blast-furnace slag, a waste from industrial, used as a binder with a Portland cement in concrete, ensure of blast-furnace slag utilization.
This thesis aims to study the basic and durability properties of concrete with ground granulated blast-furnace slag (GGBF slag). Portland cement type 1 (OPC) partially replaced with GGBF slag and limestone powder were considered.
The results showed that the GGBF slag and limestone powder concrete had smaller slump and slump loss when compared with OPC concrete specimens. While the compressive strength of concrete made from GGBF slag and limestone powder was likely to be less than or similar to that of OPC concrete. It was also found that the autogenous shrinkage and drying shrinkage of concrete with GGBF slag and limestone powder was less than that of OPC concrete specimens. While the carbonation depth of concrete made from GGBF slag and limestone powder had more than that of OPC concrete. In addition, concrete specimens made from OPC partially replaced with GGBF slag and limestone powder had superior resistance chloride penetration when compared with OPC concrete specimens. Furthermore, in the sulfate solution, the expansion of concrete with GGBF slag and limestone powder, except concrete with limestone powder, was less than that of Portland cement type 5 concrete specimens. In case of in magnesium sulfate solution, the weight loss of concrete with GGBF slag and limestone powder had more than that of Portland cement type 5 concrete specimens. Finally, the GGBF slag can be selected to use in appropriate concrete mix.
