Cement Types
In the most general sense, portland cement is produced by heating sources of lime, iron, silica, and alumina to clinkering temperature (2,500 to 2,800 degrees Fahrenheit) in a rotating kiln, then grinding the clinker to a fine powder. The heating that occurs in the kiln transforms the raw materials into new chemical compounds....
Fine Limestone in Cement: Understanding Cement
Essential viewing for anyone with technical oversight of cement manufacturing, concrete mix design/production or concrete petrography There still seems to be some confusion about whether fine limestone in cement (up to about 5% as permitted by eg: US and European standards) is an inert filler, or whether it is chemically reactive and contributes to the cement hydration products....
