Tunnelling breakthrough made easy with FRP rebar
Retrofit structural solutions based on CFRP
ASTEC Carbon Solutions is a range of 3 products based on the same innovative composite material: Carbon Fiber Reinforced Polymer. ASTEC CFRP offer amazing properties: 4 times the tensile performance of steel for only 1/4 of the weight.
In the past 20 years have emerged new structural applications for Carbon fiber based elements:
- External Bonding Reinforcement (EBR), where a carbon laminate is applied on the surface to increase the flexural and shear strength of the member.
- NSM (Near Surface Mount) applications, where a carbon rod or tape is inserted in a cut groove with cement grouting or epoxy adhesive. NSM offers a gain of 4.8x the flexural strength compared to EBR technique.
- External post-tensioning applications, where a carbon rod is installed below a concrete member thanks to state-of-the-art splicing system.
Product features
- ASTEC CFRP Repair & Strengthening range is available in 3 forms: laminate, tape and rod.
- Laminate: 50 or 100mm width with thickness of 1.4mm for an ultimate tensile load up to 336 kN.
- Tape: 16mm width and available in two thicknesses foran ultimate tensile load of 140 kN.
- Rod: 3 diameters up to 218 kN ultimate tensile load capacity. Our rod solution features innovative connectors to allow the installation as PT applications.
- Designed as per ACI440.2R-08 , ACI440.74, ACI-440.7R and FIB Task group 9.3. Tested as per ACI 440-3R-12.
