Augmenting granulated blast furnace slag (GBFS) content in Portland Slag Cement (PSC) beyond the conventional limit of 70% is the stimulus for this study. It has been classified as an amorphous material when used as a binder material and called granulated blast furnace slag and classified as a crystalline material when used as a material for road paving, called gradually-cooled blast furnace slag. Blast furnace slag is a by-product of iron manufacturing, via thermochemical reduction, in a blast furnace. Sun, S.S., Zhu, G.L., Zhang concluded that the recy- !

The addition of blast furnace slag, fly ash and/or silica fume may significantly increase the resistance against chloride penetration and consequently the time-to-initiation of corrosion. The molten slag at a temperature of about 1500°C Such enhancement other than bringing down the carbon footprint of cement conserves natural resources. geopolymer cement with better property and less CO 2 emission than the simple slag-based geopolymer cement. Ground granulated blast-furnace slag (GGBFS) has latent hydraulic properties that could be activated using suitable activators [4]. 2, 3)History of Portland Blast Furnace Slag Cement 3.1 Birth of portland blast furnace slag cement As mentioned earlier, PBFSC was developed in 1910—nine years after the government-managed Yawata Works was put into op-eration. Use of blast-furnace slag's as • Sand and gravel for the construction of road beds, • Basic filler in asphalt–concrete mixtures for the construction of road and airport coatings, • Unroasted cement (binder) for reinforcing roadways and • Preparing slow-setting concrete. Mechanically activated granulated blast furnace slag was used in the range of 20% - 75% to replace clinker in Portland slag cement.

Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. GGBS Concrete GGBS Proportions On its own, ground granulated blast furnace slag (GGBS) hardens very slowly and, for use in concrete, it needs to be activated by combining it with Portland cement. iron ore, iron sintering). Slag cement is often referred to as “ground granulated blast-furnace slag” (GGBFS). Two major uses of GGBS [2] are in the production of quality-improved slag cement, namely Portland Blast furnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70% and in the production of ready-mixed or site-batched durable concrete. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S>> Hydration kinetics and products of MgO-activated blast furnace slag Solmoi Parka,b, Hyeong Min Parkc,d, H.N.
