USA Portland cement clinker and portland cement ...

Portland cement usually consists of portland cement clinker and a sulfate carrier, usually gypsum. Portland cement clinker is prepared from a raw material mixture that contains mainly defined percentages of calcium oxide (CaO), silicon dioxide (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3). By heating this mixture to sintering, new ...
