Portland Cement Description

Definition of portland cement - American Concrete Institute

Definition of portland cement. Q. What is portland cement? A. Portland cement is the product obtained by pulverizing clinker, consisting of hydraulic calcium silicates to which some calcium sulfate has usually been provided as an interground addition. When first made and used in the early 19th century in England, it was termed portland cement because its hydration product resembled a building ...
