Two new calibration standards for use with X-ray fluorescence equipment in the chemical analysis of hydraulic cement are now available from the Cement and Concrete Reference Laboratory (CCRL). The new standards are designated Portland Cements 167 and 168 and are vacuum-sealed to prevent moisture uptake. Robin Haupt, supervisor, CCRL proficiency sample program, says that the two new cements were…

All interested parties in the glass industry are invited to participate in the development of a proposed new standard guide for the safe handling of annealed glass. The new standard will be developed by a task group within ASTM Committee E34 on Occupational Health and Safety. A small group from industry and OSHA met in Rossford, Ohio, in March to discuss this new activity. The task group plans to…

The realization that concrete production is the result of a combination of several materials that are individually standardized, but which may interact in ways not governed by those standards, led ASTM International Committee C09 on Concrete and Concrete Aggregates to form Subcommittee C09.48 on Performance of Cementitious Materials and Admixture Combinations in 2004. The subcommittee has now…

Two recently formed task groups on preparing pervious concrete specimens and research will be participating in the first meeting of the new Subcommittee C09.49 on Pervious Concrete from 8:00 to 10:00 a.m. on June 25 during the ASTM Committee Week in Norfolk, Va. C09.49 is part of ASTM International Committee C09 on Concrete and Concrete Aggregates. Heather Brown, Middle Tennessee State University…, Standardization News, , Karthik Obla, chair of Subcommittee C09.49, noted that there has been a resurgence in interest in pervious concrete due to the U.S. Environmental Protection Agency’s recent recognition of its use as a best management practice for storm water management. An increasing focus on sustainability and the green movement has also contributed to the importance of pervious concrete as a building material…
