Documents Flashcards Grammar checker. Strengthening of Cast-in-Place Concrete Section 03 01 Read in conjunction with the Contract Document.

Where a date is given for referenced standards, the edition of that date shall be used. Where no date is given for reference standards, the latest edition available on the date of the Notice of Invitation to Bid shall be used. Section 03 01 Alternate FRP system manufacturers must provide all items listed in Section 1. Only epoxy resins will be accepted for construction of FRP systems referenced in this specification.

The manufacturer shall clearly define the epoxy resin working time. Any batch that exceeds the batch life shall not be used. The list should include at a minimum 25 projects with proposed FRP system, the dates of work, description and amount of work performed. 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.

The Engineer of Record may suspend the work if the Contractor substitutes an unapproved FRP system or unapproved personnel during construction. Design and working drawings: Design shall follow criteria in Section 1. Due to the temperature sensitive nature of FRP systems, no fire resistance system shall be allowed without the aforementioned U. Products shall be stored to avoid UV exposure.

SCH fiber — primary carbon fiber, unidirectional. SEH fiber — primary glass fiber, unidirectional. Alternate primary carbon or glass fiber systems available upon request. Anchors may not be field fabricated.

ASTM D7565/D7565M – 10(2017)

They shall be manufactured and shipped directly axtm the manufacturer. Anchor labels shall have the date of manufacture, the lot number and the minimum weight per unit length for each size. Alternate finishes must be approved by the owner.

All other alternate FRP system manufacturers must provide all items listed in Section 1. Certified applicators shall have the minimum experience and written consent by the FRP manufacturer See Section 1. Existing uneven surfaces to receive composite shall be filled with the system epoxy filler or other material approved by the Engineer of Record.


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. The contact surfaces shall have no free moisture on them asttm the time of application.

If moisture is present, use the manufacturer suggested wet prime epoxy, if available.

Fill surfaces with thickened epoxy to eliminate air surface voids greater than 0. Well-adhered paint and concrete do not require removal. Variations in the radius along the vertical edge shall not exceed 0.

All contact surfaces shall then be cleaned by hand or compressed air. Provide anchorage as detailed on construction drawings, if required. Variations in the radius along the edge shall not exceed 0. Visit site to ensure that all patch work is complete and cured. Review project specifications in detail.

The components of epoxy resin shall be mixed with a mechanical mixer until uniformly mixed, typically 5 minutes at rpm. Fabric shall be completely saturated prior to application to contact surface in order to ensure complete impregnation.

Saturation shall be supervised and checked by the certified installer. Both the epoxy resin and fabric shall be measured accurately, combined, and applied uniformly at the rates shown on the approved working drawings and per manufacturer’s recommendations. Allow primer to become tacky to the touch. Atsm certain application conditions, the system may be placed entirely by hand methods assuring a uniform, even final appearance.

Gaps between composite bands may not exceed 0. All edges and seams must be feathered. Finish as specified between 24 and 72 hours after final application of epoxy. If finish is provided beyond 72 hours of the application of the epoxy, the surface must be roughened by hand sanding or brush blasting, prior to finishing.

Record batch numbers for fabric and epoxy used each day, and note locations of installation. Measure square footage of fabric and volume of epoxy used each day. Complete report and submit to Owner, engineer-of-record and FRP composite system manufacturer.


All defective areas shall be repaired as per Section 3. Pulloff tests shall be performed on a representative adjacent area to the area being strengthened whenever possible. Tests shall be performed on each type of substrate or for each surface preparation technique used. The locations of the pull-off tests shall be representative and d765 flat surfaces. If no adjacent areas exist, the tests shall be conducted on areas of the installed FRP system subjected to relatively low stress during service.

The average of the tests shall not be less than psi psi for masonry. Additional tests may be performed to qualify the work at each identified area. Each pull-off test is to exhibit a failure mode in the substrate and not the epoxy-tosubstrate bond plane.

Then place one layer of saturated fabric and apply additional topping of epoxy. Cover with plastic film and squeegee out all bubbles. The prepared, identified samples shall be given d7556 a pre-approved and experienced testing laboratory. If one coupon does not achieve the design properties, additional coupons from the same sample shall be tested. If these coupons fail on averagecoupons from the other inch-byinch sample, from the same batch for that day, shall be tested.

If all tested samples of the sample batch do not meet the conditions of acceptance, it is recommended that 25 percent of all samples be tested. Acceptable minimum astk 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 astk capacity as per the original design demands and concept. Any structural member 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.
