Slag cement is commonly found in readymixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial byproduct of an iron blast furnace. Molten slag diverted from the iron blast furnace is rapidly chilled, producing glassy granules that yield desired reactive cementitious characteristics when

On the maintenance side cement plants need a wide array of parts such as refractories, motors, lubricants, gears, wear parts for mills, ball bearings and so forth. Some of these may have more complicated supply chain routes than they used to have 30 years ago. On the supplier side any new or upgrade plant project is vulnerable if necessary parts are delayed by a production halt, logistics

cement paste (hcp) will have a high degree of capillary porosity. Since the capillary pores can be quite large, the high degree of capillary porosity, greatly weakens the hcp. This is why concrete from mixes with high watercement ratios tends to be weaker than concrete from mixes with watercement ratios in the vicinity of to B. Admixtures

belite: the substitution of cement by both slags seems to result in a delay in the hydration of belite in the first days. aluminate phase: there is a filler effect using inert filler at about 12 hours of hydration, which shows slag can also has filler effect in the early hydration period. Transformation of AFt to AFm causes cumulative heat shoulder at about 60 hours.
