Committee Seeks Concrete Stakeholders to Develop New Standards for Bond Breakers

ASTM Committee C09 on Concrete and Concrete Aggregates invites professionals involved in concrete construction and/or coatings to develop standards for concrete bond breakers.

A task group of Subcommittee C09.22 on Bond Breakers will write minimum performance standards for bonding agents related to parting ease, curing properties, compatibility with subsequent coating, and other applications.

The proposed standards can “reduce liability for the manufacturers and contractors alike in the industry—while enhancing owner value and quality outcomes for this type of construction—and elicit better behavior relative to product advertising,” says task-group chairman Todd Fraker, national accounts and specification manager, Dayton Superior Chemical and Cement Products, Commerce City, Colo.

Fraker says the need for new standards arose because “the tilt-up method of construction has become more prevalent in the construction industry (over 400 million sq. ft. in 2001). As a result, the use of bond breakers has soared along with design professionals need for information concerning compatibility with other coatings, curing properties, etc.”

For further technical information, contact Todd Fraker, Dayton Superior Chemical and Cement Products, Commerce City, Colo. (phone: 800/745-3708). Committee C09 meets Dec. 8-11 in Miami Beach, Fla. For membership or meeting details, contact Jim Olshefsky, director, Committee Services, ASTM International (phone: 610/832-9714). //
