FRP Specifications – Concrete Solutions
The Engineer of Record may suspend the work if the Contractor substitutes an unapproved FRP system or unapproved personnel during construction. Any batch that exceeds the batch life astk not be used. Gaps between composite bands may not exceed 0. Filling of large voids in surfaces to receive composite shall be paid as an extra to the contract work of installing the composite system small pinholes or micro-bubbles in the concrete surface or resin do not require special detailing.
Alternate primary carbon or glass fiber systems available upon request. Any structural qstm where the installed FRP system does not meet the Acceptance Criteria, additional layers shall be installed until the FRP meets design requirements, or any other remediation directed by the Engineer of Record.
Tests shall be performed on each type of substrate or for each surface preparation technique used. Link to Active This link will always route to the current Active version of the standard.
ASTM D7565 Tensile Properties of FRP Matrix Composites for Civil Structures
Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
The composite material forms are limited to continuous fiber or discontinuous fiber-reinforced composites in which the laminate is balanced and symmetric with respect to the test direction. Read in conjunction with the Contract Document. Acceptable minimum values for ultimate tensile strength, tensile modulus, and elongation shall not be below the submitted design values unless calculations are performed using the tested values that exhibit an acceptable capacity as per the original design demands and concept.
D Terminology for Composite Materials.
Provide anchorage as detailed on construction drawings, if required. No items in cart.
Please login to your authorized staff account to use this feature. If one coupon does not achieve the design properties, additional coupons from the same sample shall be tested.
They shall be manufactured and shipped directly from the manufacturer. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. We are confident that we have what you are looking for. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.
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. Alternate FRP system manufacturers must provide all items listed in Section 1. Other components used to attach the FRP material to the substrate, such as the primer, putty, and adhesive in externally bonded strengthening systems, are excluded from the sample preparation and testing detailed in this document.

Well-adhered paint and concrete do not require removal. Leave the site clean. Land Use and Development.
Pre-faced Concrete Unit Masonry. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The certified applicator shall prove a minimum of 5 years experience in performing retrofits using FRP systems and submit a list of no fewer than 15 successful installations.
Both the epoxy resin and fabric shall be measured zstm, combined, and applied uniformly at the rates shown on the approved working drawings and per manufacturer’s recommendations.
Existing uneven surfaces to receive composite shall qstm filled with the system epoxy filler or other material wstm by the Engineer of Record. Combining values from the two systems may result in nonconformance with the axtm.
SCH fiber — primary carbon fiber, unidirectional. All defective areas shall be repaired as per Section 3. If no adjacent areas exist, the tests shall be conducted on areas of the installed FRP system subjected to relatively low stress during service. D Terminology Relating to Plastics.

All contact surfaces shall then be cleaned by hand or compressed air. Products shall be stored to avoid UV exposure. The components of epoxy resin shall be mixed with a mechanical mixer until uniformly mixed, typically 5 minutes at rpm. Certified applicators shall have the minimum experience and written consent by the FRP manufacturer See Section 1. All edges and seams must be feathered.
