C12 – 1.5 x 1.5

Carbon Fiber Reinforcing Grids for Concrete Structures

DESCRIPTION C-GRID® C12 – 1.5 x 1.5 is one of the C12 Series of medium strength carbon fiber grid for reinforcing concrete structures.

Features

Applications

Non-corrosive; can be used with as little as
1⁄4” (6 mm) of cover

Cast stone reinforcements

Requires less concrete cover leading to
lighter structures

Concrete countertops

Lightweight, easy to handle and use; can be
cut to fit using conventional tin snips

Thin topping slabs and overlays

Decorative concrete applications

High tensile strength and modulus
Outstanding mechanical bond with concrete;
requires a minimum of 1⁄4” (6 mm) to develop
its strength

PHYSICAL PROPERTIES
carbon fiber and epoxy resin

Application Use Note: C-GRID® remains a relatively novel material without the extensive performance history of traditional construction materials. Reported properties are average values, not design values. Structures and applications
using C-GRID® should be designed using appropriate safety factors or load and strength reduction factors. All applications utilizing C-GRID®, including critical life safety and fire rated structures, should be designed and reviewed by a
licensed engineer experienced with FRP materials. The data expressed herein is believed to be accurate at the time of publication; however, it is subject to change without notice.

Notes:
Centerline-to-centerline spacing between strands is nominal and based on the average number of strands per unit width. Actual spacing may vary by ± 0.10” (± 2.5mm).
Individual strand cross-sectional area is normalized to the cross-sectional area of the fibers in accordance with ACI 440.2R. The actual measured thickness and width are larger and shall not be used for design purposes.
The longitudinal direction is in the direction of the roll, and the transverse direction is across the width of the roll. For example, if a roll of C-GRID® is 36” wide, the carbon strands in the transverse direction are 36” in length. If a
roll of C-GRID® is 500 yards long, the longitudinal strands are 500 yards in length.
Reported tensile strengths are based on the average minus two standard deviations (AVG-2s) of a large population of test results.
Tensile modulus values are based on properties reported by the carbon fiber supplier. C-GRID® exhibits linear elastic behavior, so failure strains are estimated using Hooke’s Law.
