Slag powder is high-performing admixture for concrete in that it increases the concrete's ability to resist compression, tension, shear, and bending stresses. A major trend that characterizes the building material industry is to replace equal amount of cement with slag powder in making concrete or cement products.
Augmenting granulated blast furnace slag (GBFS) content in Portland Slag Cement (PSC) beyond the conventional limit of 70% is the stimulus for this study. Such enhancement other than bringing down the carbon footprint of cement conserves natural resources. However, beyond 70% slag incorporation, early strength gain of PSC is …

concrete, GGBFS mainly competes with fly ash, metakaolin, and volcanic ash pozzolans. In this respect, GGBFS reduces the amount of portland cement per ton of concrete, thus allowing more concrete to be made per ton of portland cement. Slags (especially steel slag) can be used as a partial substitute for limestone and some other natural

Three slag slurries with different fineness were prepared through milling with varying duration (20 min, 40 min and 60 min, abbreviated as S2, S4 and S6, respectively). The reaction kinetics, mechanical properties, hydration products and microstructure of hardened GGBFS …
slag cement (GGBFS) are considered cementitious materials. 2. Supplementary Cementitious Materials – A pozzolanic material which is used in replacement of cement to enhance or supplement the properties of the concrete. Some typical enhancements from the addition of these materials are concrete durability and strength. In this
Slag in Concrete Definition: granulated blast-furnace slag that has been finely ground and that is hydraulic cement.- ACI Concrete Terminology The use of slag in concrete has several benefits, including reduced energy, reduced greenhouse gas …
For example, in additive cement production, the blast furnace slag has to be ground to Blaine values of 5,000 cm 2 /g. Water demand and setting times are similar to that of a ball mill cement under comparable …
