The use of rolling devices can provide a means to evaluate the adhesion of weather seals, for quality control in new installations, general evaluation of existing installations, and the investigation of water and air leakage through building enclosures. In order to better facilitate the use of rolling devices, ASTM International Committee C24 on Building Seals and Sealants is developing a…

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…

ASTM International Committee B05 on Copper and Copper Alloys has created a new task group, TG9018, which will be focused on the Antimicrobial Applications of Copper and Copper Alloys. The task group was formed following the U.S. Environmental Protection Agency's announcement of its registration of copper alloys as antimicrobial materials with specific health claims. According to James Michel,…

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…

Applications are currently being accepted for the 2008 ASTM International Katharine and Bryant Mather Scholarship. Administered by ASTM International Committee C09 on Concrete and Concrete Aggregates, the scholarship applies to students pursuing degrees specializing in cement or concrete materials technology or concrete construction. Full-time undergraduate students completing their second/…

A proposed new standard being developed by ASTM International Committee C09 on Concrete and Concrete Aggregates will monitor clogging and long-term permeability of pervious pavements as well as determine if early sealing of the pavement has occurred during construction. This proposed standard, WK17606 , Test Method for Permeability of Pervious Concrete Pavements, is under the jurisdiction of…

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…
