Three primary factors define the success or failure of any attempt to forcibly penetrate a security fence system: the tools and devices employed, the number of aggressors and their level of sophistication. A newly approved ASTM International standard can be used to measure the resistance of fence systems to such an attempt. ASTM F2781 , Practice for Testing Forced Entry Resistance of Security…, ASTM Committee F14 Next Meeting:, Feb. 16, 2010 , in conjunction with American Fence Association, FENCETECH 2010, Orlando, Fla., Technical Contact:, Charles Naegele, P.E., Allied Consulting Inc., Clarks Summit, Pa., Phone: 570-586-7260; canaegele@aol.com, ASTM Staff Contact:, Thomas O’Toole, Phone: 610-832-9739; totoole@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8427/Dec2009

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…
