Non-destructive moisture meters are now widely used in determining moisture levels in concrete, gypsum concrete and other types of floor slabs. A new ASTM International standard qualifies the types of meter suitable for this purpose and provides guidelines for how, where and when such moisture meters are used and what limitations exist. The new standard, ASTM F2659 , Guide for Preliminary…, ASTM Committee F06 Next Meeting:, Nov. 10-11, New Orleans, La., Technical Contact:, Sean Fallon, Dublin, Ireland, Phone: +011-353-1-285-1861; seanfallon@ireland.com, ASTM Staff Contact:, Stephen Mawn, Phone: 610-832-9726; smawn@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #870/Oct2010

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…
