This specification covers the criteria and tests to be used for determining whether a processing addition meets the requirement. When proposed addition is accepted for general use in Portland cement, tests shall be made on cements prepared from at least five different clinkers. These clinkers shall represent two Type I cements, one Type II cement, and two Type III cements. Processing additions shall be evaluated by comparing cements containing the addition to otherwise identical cements from the same source without the addition, or containing a processing addition. The compressive strength and flexural strength of the concrete made with cement containing the addition shall be compared with strengths obtained with the control cement at similar ages. The properties of the materials shall be determined through the following tests in accordance with the following standard: chemical analysis of the cement, compound composition, fineness of cement, normal consistency, time of setting, autoclave expansion, air content of mortar, compressive strength of mortar, and drying shrinkage of mortar.
