How Cement Is Made Portland Cement Association
Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore. These ingredients, when heated at high temperatures form a rock-like substance that is ground into the fine powder that we commonly think of as cement.

Grindability is of major importance in the manufacture of slag blended cement. In terms of grindability, BFS is slightly more abrasive than clinker and cogrinding has to be performed with care Alanyali et al., 2009. The laboratory results are inconclusive in determining the efficiency of intergrinding steel slag
What is Slag Cement with pictures wiseGEEK
Feb 07, 2021 Slag cement, often called ground granulated blast-furnace slag GGBFS, is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.

Ground-granulated blast-furnace slag GGBFS is produced by quenching molten iron slag a by-product of iron and steel-making from a blast furnace in water, to produce a granular product that is then dried and ground into a fine powder.
Low CO2 Concrete
Slag cement requires nearly 90 percent less energy to produce than an equivalent amount of Portland cement. Reducing the use of Portland cement in concrete by substituting a portion of it with slag reduces the embodied energy in a cubic yard of concrete by 30 to 48 percent.

Portland Slag Cement All You Like to Know
Slag is a by-product of the manufacture process of pig iron. It is a mixture of lime, aluminate and silica, which are the main components of OPC. The slag shows cementitious properties when it reacts with water. Hence, the by-product can be easily blended with OPC to produce PSC cement.
