Evaluation of Ground Granulated Iron Blast-Furnace Slag: Grade 100
Currently, the use of grade-120 Granulated Ground Blast Furnace Slag (GGBFS) is incorporated into the specifications of LA DOTD concrete mixes. This study evaluates grade-100 GGBFS and its effect on the properties of hydraulic cement concretes used in structures and pavements construction. Four mix designs were used for this study, two structural and two pavements, with varying amounts (15%, 30%, and 50%) of grade-100 GGBFS used as a by-weight substitution for cement. Additionally in order to simulate field conditions, the study used three different temperatures (50 F, 73 F and 90 F) for the components at mixing and curing conditions. This study looked at the effects of slag on workability, durability, and the compressive and flexural strengths of the concrete. How grade-100 GGBFS compared to grade-120 GGBFS in its effect on the concrete's physical properties and set times was also crucial in determining its acceptability for LA DOTD concrete structures and pavements.
