New ASTM Standard helps ensure wire bonding quality in concrete.
Press Release Summary:
Mar 09, 2016 - To enhance specification in purchases as well as standardized testing, Test Method for Evaluating the Bond Quality of Steel Wire for Concrete Reinforcement will be published as A1096. This standard will help establish acceptable bond range corresponding to specific needs ofÂ prestressed concrete manufacturers that use steel wires in their products.Â Test described in A1096 is based on ASTM standard A1081, Test Method for Evaluating Bond of Seven-Wire Steel Prestressing Strand.
Original Press Release
New ASTM Standard Will Help Ensure Bonding Quality of Wires in Concrete
Press release date: Mar 04, 2016
The new standard is soon to be published as A1096, Test Method for Evaluating the Bond Quality of Steel Wire for Concrete Reinforcement. In developing the standard, a variety of wire geometries from different global suppliers were used. The test described in the new standard is based on ASTM standard A1081, Test Method for Evaluating Bond of Seven-Wire Steel Prestressing Strand.
Peterman notes that a Kansas State University research team found that wires with low bond quality can lead to structural deficiency while wires that bond too quickly – often those near the surface of the concrete – can cause longitudinal splitting along the wires. The new standard will help establish an acceptable bond range that corresponds to the specific needs of a prestressed concrete manufacturer, allowing for better specification in purchases and better standardized testing.
An ASTM section on prestressing steels developed the new standard. ASTM member Christopher Reeve, a metallurgical engineer with Insteel Wire Products, the section chairman invites participation from all parties interested in helping to develop and maintain standards related to single prestressing wire, epoxy-coated strand, compacted strand, indented strand, two- and three-wire strand and related products.
