- ASTM International
This specification pertains to blended hydraulic cements for both general and special applications, using slag or pozzolan, or both, with portland cement or portland cement clinker, or slag with lime. These cements are classified into two types: Type IS which is portland blast-furnace slag cement and Type IP which is portland-pozzolan cement. They can also be described according to air-entraining, moderate sulfate resistance, moderate heat of hydration, high sulfate resistance, or low heat of hydration properties. In addition, the cement shall undergo different tests to determine properties such as: chemical analysis, fineness by sieving, fineness by air-permeability, autoclave expansion, time of setting, air content of mortar and compressive strength. Additional optional testing such as heat of hydration and sulfate resistance is also included.
This standard is referenced in the 2012 International Building Code® and the International Residential Code®.
