PORTLAND CEMENT CLINKER By William Lerch 1 ABSTRACT The approximate glass content was determined, by the heat of solution method, for commercial portland cement clinker obtained from 21 plants throughout the United States. The approximate glass content of these commercial clinker com­ positions was found to vary from 2 to 21 percent.

Portland cement clinker

Portland cement clinker is a dark grey nodular material made by heating ground limestone and clay at a temperature of about 1400 °C - 1500 °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.
