Among the proposed new standards that ASTM Committee E05 on Fire Standards is currently working on are two that cover aspects of fire exposure. Committee E05 is meeting in Atlanta in December and welcomes participation in its standards developing activities., Roof Field Vent Response, Embers from wildfires can travel through the air up to four miles away from the fire source, particularly in areas where wind is often prevalent during fire season. These embers can then enter structures through ventilation systems and other openings in a building envelope, resulting in fires being ignited from within a structure. A proposed new ASTM standard will cover a test for the resistance…, Fire Response, Subcommittee E05.14 is also working on ASTM WK25760 , Guide for Quantification of Fire Exposures. The proposed standard will cover fire exposure metrics that will be used in the development of fire test methods. According to Jon Traw, president, Traw Associates Consulting, and chairman of Task Group E05.14.08, the proposed standard will serve as a critical tool in the development of appropriate…, ASTM Committee E05 Next Meeting:, Dec. 6-9, ASTM Committee Week, Atlanta, Ga., Technical Contacts:, (WK23700) Gregory Daniels, O’Hagin’s Inc., Rohnert Park, Calif., Phone: 707-303-3660; gdaniels@ohaginvent.com ; (WK25760) Jon Traw, Traw Associates Consulting, Whittier, Calif., Phone: 562-789-7583; trawassoc@yahoo.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 #8423/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…
