SECTION 03 21 11

Basalt Fiber Reinforced Polymer (BFRP) rebar for Concrete Reinforcement according to ASTM D7957.

Specifier Notes: This section covers Basalt Engineering, LLC. – BASTECH® – Basalt Fiber Reinforced Polymer Rebar (BFRP Rebar)

BFRP Rebar is an alternative to galvanized or epoxy coated rebar, stainless steel rebar or GFRP rebar. BFRP rebar should be considered for any concrete member susceptible to corrosion of steel reinforcement by water, salt water, deicing salts or other corrosive agents as BFRP Rebar DOES NOT CORRODE. Other advantages of specifying BFRP Rebar: 4.5 times lighter than steel rebar, tensile strength is 2.5 times stronger than steel rebar, up to 30% less concrete coverage required versus steel rebar (subject to design), transparent to radio frequencies, non-conductive, non-magnetic, same thermal coefficient as concrete, dielectric, UV resistant, BFRP Rebar can withstand temperatures from -50 C to 300 C, less shipping costs, easier to handle, easier to cut, less cost than stainless steel rebar. Life span is 100 plus years in comparison to 50 years for steel rebar.

BFRP Rebar applications as an alternative to steel rebar: bridges, tunnels, seawalls, highways, mining, median barriers, approach slabs, parking structures, salt storage facilities, railroad grade crossings, precast, ports, airports, transformer sub stations, underground utilities, foundations, concrete tanks, submerged concrete structures, floating marine docks, aquaculture projects, MRI rooms, swimming pools, ice skating arenas.

1.4 DESIGN REQUIREMENTS

Specifier Notes: Design with BASTECH® – Basalt Fiber Reinforced Polymer Rebar (BFRP Rebar) shall be in accordance with ACI publication ACI 440.1R “Guide for the Design and Construction of Concrete Reinforced with FRP Bars” for building structures. For transportation structures, use AASHTO LRFD Bridge Design Guide Specifications for FRP – Reinforced Concrete, 2nd Edition December 2018. Alternatively, by the provisions of the Canadian Highway Bridge Design Code Section 16. Canadian Standards Association, CSA S806-02 Design and Construction od Building Components with Fiber Reinforced Polymers, Interim design guidelines have been published by the British Institution of Structural Engineers coving modifications to BS8110 and BS5400, the Norwegian Concrete Standard NS3473, and the Japanese Society of Civil Engineers.

In general, the designer shall consider the following:

1. Do not substitute BFRP reinforcing bars for steel reinforcing bars on an equal area basis, due to differences in material properties.
2. Specifically design reinforced concrete members for BFRP rebar, taking into account properties of the material and effects, on strength, deflection and crack width.
3. In most cases, deflection will control design of concrete structures reinforced with BFRP rebar based on value of modulus of elasticity of BFRP rebar.
   
   

1.5 SUBMITTALS

1. Comply with Section 01330 – Submittal Procedure
2. Product Data: Submit manufacturer’s product data, including material and mechanical properties.
3. Test Reports: Submit manufacturer’s certified test reports for source quality control testing for material and mechanical properties performed either in house or by an independent testing agency. If independent testing is required, this shall be noted at the time of bidding.

1.6 QUALITY ASSURANCE

Specifier Notes: Describe requirements for the placement and tolerances of BFRP rebar in the formwork.

A. Placing of the BFRP rebar, handing and tolerance in formwork shall be in accordance with ACI 440.5-18 “Specification for Construction with Fiber-Reinforced Polymer Reinforcing Bars”. Reported be ACI Committee 440, July 2018.

1.7 DELIVERY, STORAGE AND HANDLING

Specifier Notes: Care should be taken to avoid damaging the surface of the rebar by abrasion, nicks, or cuts.

1. General: Deliver, store and handle BFRP rebar in accordance with manufacturer’s instructions to prevent damage and in accordance with ACI 440.5-18 “Specification for Construction with Fiber Reinforced Polymer reinforcing rebar. Reported by ACI Committee 440, July 2018.
2. Storage: Do not store BFRP rebar directly on the ground. Place rebar on timbers or pallets to keep free from dirt and mud and to provide easy handling.
