January 19, 2012 - ASTM WK35250, Practice for Fiber-Reinforced Concrete for Making and Curing Test Specimens in the Laboratory and Field, being developed by Subcommittee C09.42 on Fiber-Reinforced Concrete. This proposed standard will provide proper direction and ensure adequate documentation to aid in interpretation, understanding, and reduction of variance in test results for fiber-reinforced concrete. Specifically, it describes testing done by means of external vibration.

W. CONSHOHOCKEN, Pa.-A proposed new ASTM standard will provide proper direction and ensure adequate documentation to aid in the interpretation, understanding and reduction of variance in test results for fiber-reinforced concrete.

ASTM WK35250, Practice for Fiber-Reinforced Concrete for Making and Curing Test Specimens in the Laboratory and Field, is now being developed by Subcommittee C09.42 on Fiber-Reinforced Concrete, part of ASTM Committee C09 on Concrete and Concrete Aggregates.

"Fiber-reinforced concrete is not the same as ordinary Portland cement concrete in terms of simple fabrication," says Clifford MacDonald, fellow of the American Concrete Institute, and director of engineering, FORTA Corp., as well as chairman of the task group developing ASTM WK35250. "There are specific issues that need to be addressed to ensure consistency in making specimens for testing. At this time, there are limited and/or inconsistent practices instructing the industry on how to make FRC specimens."

MacDonald also notes that current standards for other types of concrete test samples involve rodding or internal vibration, both methods that can lead to non-uniform fiber concrete. Both of these conditions increase variance between test results.

ASTM WK35250 describes testing done by means of external vibration, which is effective for fiber-reinforced concrete. Testing agencies and those who specify testing of fiber concrete will use the proposed standard, once it has been approved. Fibers can be used in any concrete, and particularly fiber reinforced concrete is used in precast applications, industrial floor slabs, composite metal decks, blast containment structures, overlays, tunnels and many other applications.

All interested parties are invited to participate in the development of ASTM WK35250.
