Type III High Early Strength. Type IV Low Heat Hydration. Type V High Sulfate Resistance. For blended hydraulic cements – specified by ASTM C595 – the following nomenclature is used: Cement Type Description. Type IL Portland-Limestone Cement. Type IS Portland-Slag Cement. Type IP Portland-Pozzonlan Cement.

The portland cement nomenclature is the same as C 1157. The blended cement nomenclature builds off those designations. As with the ASTM specifications, white cement could be specified under the portland cement designation, but would not likely be specified under the blended cement specifications. See CSA Group for more information.
