Actual spacing may vary slightly. 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 47.5” wide, the carbon strands in the transverse direction are 47.5” in length. If a roll of C-GRID ® is 500 yards long, the longitudinal strands are 500 yards in length. Reported tensile strengths are typical values from testing. These values should not be used for design purposes. The individual product data sheets should be consulted for design values that have been statistically adjusted. 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. Individual product data sheets should be consulted for a complete list of mechanical and physical properties. In as much as Chomarat has no control over installation design, installation workmanship, accessory materials, or conditions of application, Chomarat does not warrant the performance or results of any installation use of C-GRID ®.

The purchaser and/or user should perform its own tests to determine the sustainability and fitness of the product for a particular purpose desired in any given situation. (03/2010) Legend: A = Excellent Resistance Should be suitable for all applications where this chemical environment exists. B = Good Resistance Should be suitable for most applications. Some degradation of the epoxy resin may occur after extended, direct exposure of the grids to this chemical environment. If the intended application results in extended, direct exposure to this chemical environment, the user is advised to conduct tests to determine the suitability of the carbon grids to this environment. C = Fair Resistance Should be suitable for applications where only limited, intermittent, direct exposure to this chemical environment is allowed. Embedding in concrete may improve the resistance. The user is advised to conduct tests representing the actual construction details to determine the suitability of the carbon grids to this environment. D = Poor Resistance Direct exposure to this environment may cause degradation of the carbon fibers leading to a loss in tensile strength. Not recommended.
