Associations in the Mix

NRMCA The National Ready Mixed Concrete Association has hired Jon Hansen and Doug O'Neill to join its team of national resource directors. The association also has hired Erin Ashley as director of codes and sustainability, and has promoted Eileen Dickson to senior director of education and Lawrence Afable to senior director of information technology.

NRMCA also has started a new Web site, www.concretehelp.org, to provide engineers, architects, developers, and builders a resource hub for all ready mixed concrete inquires.

ACI The American Concrete Institute (ACI) has started a free electronic membership program for college students. The ACI Student E-Membership program was designed to expose students to the benefits of ACI and reaches out to a wide network of instructors at universities and colleges, as well as industry professionals.

“We hope that this free membership will be the first step toward a career-long commitment to ACI upon graduation and entrance into the industry workforce,” said Diane Baloh, ACI's director of marketing and membership. For more information, visit www.students.concrete.org.

ASTM ASTM Committee C-9 on Concrete and Concrete Aggregates will hold a planning meeting for some proposed new standards on pervious concrete when it meets in Atlanta on Dec. 4. The committee is especially seeking researchers who have been experimenting with different types of tests for pervious concrete, as well as specifying engineers, concrete technologists, and contractors. Contact Karthik Obla at 210-485-1163, or e-mail kobla@nrmca.org, or James Olshefsky at 610-832-9714, or e-mail jolshefs@astm.org.

A new standard, C 1610/C 1610M, “Test Method for Static Segregation of Self-consolidating Concrete (SCC) Using Column Technique,” satisfies a need for a test method to measure the stability of SCC. The standard is under the jurisdiction of Subcommittee C09.47 on SCC, which encourages contributions and input from concrete producers and testing labs in round robin testing for C 1610/C 1610M, as well as in the development of new SCC standards.
