Portland cement clinker-overview. Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 Â°C - 1500 Â°C. The nodules are ground up to a fine powder to produce cement, with a small amount of gypsum added to control the setting properties.This page gives a thumbnail sketch.ortland cement clinker contains four principal minerals: 1  Alite: approximately tricalcium silicate (typically about 65% of the total). 2  Belite: approximately dicalcium silicate (typically about 15% of the total). 3  Aluminate: very approximately tricalcium aluminate (typically about 7% of the total).
