1.1 This specification covers methods to investigate the effectiveness of a material to beneficially change the properties of hydraulic cements when the material is incorporated during manufacture of the cement.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 The effect of additions in cement may markedly change properties other than those they are intended to modify. This specification is designed to test for such changes.
Table 1 sets forth values for those properties of cement pastes and mortars that would permit a judgment of the changes effected by an addition. Likewise,
Table 2 sets forth similar criteria for concrete. Certain additions may be found effective for more than one purpose as indicated in
3.1.4 and
3.1.5.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
