Discovering how differences between two versions of a product will affect that product’s performance continues to be a challenge for sensory professionals. However, in the past 30 years, the testing method known as the Tetrad test has begun to emerge as a means of saving companies money by enabling more information to be extracted from smaller product tests. ASTM International Committee E18 on…, ASTM Committee E18 Next Meeting:, Nov. 1-4, 2011, October Committee Week, Tampa, Fla., Technical Contact:, John M.

Rapid hardening hydraulic cements are used in a variety of applications in which reduced cementitious contents are desired or early service is needed. Included among these applications are paving, construction, stucco, mortar and block. A newly approved ASTM International standard covering these cements, ASTM C1600/C1600M , Specification for Rapid Hardening Hydraulic Cement, has been developed by…, Type URH, —ultra rapid hardening, for use where ultra high early strength is desired;, Type VRH, —very rapid hardening, for use where very high early strength is desired;, Type MRH, —medium rapid hardening, for use where mid-range rapid hardening, high early strength is desired; and, Type GRH, —general rapid hardening, for use when the higher strength properties of Type VRH or a Type MRH cement is not required. “ASTM C1600 lists minimum requirements for compressive strength, setting time, shrinkage and soundness (autoclave expansion),” says Hicks. “Optional specifications for sulfate expansion, alkali silicate reactions with aggregates, heat of hydration and expansion in water are also…
