Abstract

Ground Granulate Blast Slag (GGBS) is a very fine pozzolanic powder is by-product of the manufacturing of iron in a blast furnace. In this research, GGBS was used in self-compacting concrete (SCC) mixes as a partial cement replacement in various quantities mixed as a blended material with pure OPC. All the GGBS blended combinations were compared to a controlled mix, made with 100% pure OPC mix. This search investigates the properties of SCC as well as the effects of sustainability by testing the workability and the strength of concrete made with partial cement replacement GGBS. Some of the experiments were carried out such as: slump, workability, the compressive and tensile strength, air porosity, density and rheology. The strength values achieved were typical of structural capacity, specifically made for buildings, highway and railway bridges,
something in the order of 40 MPa and above after curing 28 days. consequently, the materials used in the lab have resulted in sustainable forms of concrete with reduction of the cement.
