Uganda proposed DUS 2093: 2018, Carbon and Glass Fibre Reinforced Polymer bar materials for concrete reinforcement – Specification Uganda National Bureau of Standards proposed Uganda Standard describes permitted constituent materials, limits on constituent volumes, and minimum performance requirements for carbon and glass fibre reinforced polymer (FRP) bars to be used as reinforcement for non‑pre-stressed concrete. Only carbon and Glass FRP bars are covered by this specification. FRP bars made of more than one fibre type (hybrid FRP) are not covered by this specification. Pultruded FRP bars with no external surface enhancement (that is, plain or smooth bars) to facilitate bond with concrete are not covered by this specification. Similarly, hollow FRP bars are not considered due to lack of documented performance as reinforcement for concrete. Plain FRP bars used as dowels (that is, devices that transfer shear across concrete joints) where the intended function requires slip of the dowel are not covered by this specification. This specification does not cover pre-manufactured grids and gratings made with FRP materials. FRP mats resulting from assembly of deformed FRP bars, however, are covered by this document. The specification also does not cover FRP bars when used for external and near-surface-mounted strengthening applications. The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification Products covered: Carbon reinforced polymer bars, Glass fibre reinforced polymer bars, Cyclic polymers of aldehydes HS code: 291250, 3901 Proposed date of adoption: March, 2019 Proposed date of entry into force: NA Final date for comments: 22-12-2018 |
