ASTM WK43339

    Work Item: ASTM WK43339 - New Specification for Deformed Glass Fiber-Reinforced Polymer Bars for Concrete Reinforcement

    (What is a Work Item?)

    Developed by Subcommittee: D30.10 | Committee D30 | Contact Staff Manager



    1. Scope

    1.1 This specification covers deformed glass fiber-reinforced polymer (FRP) bars for concrete reinforcement in cut lengths and bent shapes. The standard sizes and dimensions of deformed bars and their number designations are given in Table 1. The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables) shall not be considered as requirements of the specification. 1.2 Only FRP bars made of glass are covered by this specification. Mats comprising the assembly of deformed FRP bars are also included in this specification. 1.3 The following FRP materials are not covered by this specification: 1.3.1 FRP bars made of more than one fiber type (hybrid FRP), 1.3.2 Pultruded FRP bars with no external surface enhancement (that is, plain or smooth bars) to facilitate bond with concrete, 1.3.3 Plain FRP bars used as dowels (that is, devices that transfer shear across concrete joints) in which the intended function requires slip of the dowel, and 1.3.4 Premanufactured grids and gratings made with FRP materials. 1.4 This specification is applicable for orders in either inch-pound units (as Specification DXXYY) or in SI units (as Specification DXXYYM). 1.5 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    This standard will be used by the architects, engineers, contractors, and building and bridge owners that specify composite FRP bars in civil structures. It is of considerable importance in standardizing and subsequently advancing the market for these products.
