Recently, Concrete quality and performance as well as concrete factory unit of cement weight reduction through the concrete production cost savings for the plan as a silica fume, fly ash, blast furnace slag, such as the various mixed re-use of research on the development has been actively.
In this study, we have reviewed cement types and the activity of blast-furnace slag to enhance the activity of blast-furnace slag.
Cement types which were used in this study are high fineness cement, high early strength cement, Alumina cement and we have measured properties like slump-flow, compressive strength, pH.
Regardless of cement types, there were no big difference in aspect of flowability and it shows high reliability in age 1 day and age 3 day according to result of correlation between pH and compressive strength. In case of using high fineness cement, we found possibility to be strength performed.
