** NOTE TO SPECIFIER ** Carboplate E 170 is a range of pultruded carbon fiber plates, with high resistance and flexibility, for plating pre-stressed reinforced concrete and steel structures. Carboplate E 170 is used for the repair and upgrade of beams and slabs with increased live loads, for reinforcing concrete structures damaged by time and natural causes, and for anti-seismic strengthening of structures built on earthquake zones. Some application examples include an increase in static and/or dynamic loads brought on by equipment and machinery in industrial and commercial structures, increased traffic volume on bridges, and vibrating.
Maperoc C is a rage of pultruded carbon fiber rods, with high tensile strength and a modulus of elasticity of 22.5 x 106 psi (155,000 N/mm2). After the plastic film is removed, the Maperoc C "near surface-mounted" rods are used for structural repairs and strengthening of structural elements in reinforced concrete, brickwork, stone or volcanic ash that has been damaged by either physical/mechanical stresses or natural events. Maperod C may be used together with the fabrics from the MapeWrap(TM) range for stronger anchoring, particularly when flexural or shear strengthening operations are carried out.
MapeWrap C Uni-Ax 300 is a high-strength, uni-directional carbon fiber fabric that, when used with the MapeWrap family of two-component epoxy adhesives, forms an externally bonded fiber-reinforced polymer (FRP) reinforcement system engineered to increase the strength of existing structural elements. MapeWrap C Uni-Ax 300 is applied to the surface of structural members in buildings, parking garages, bridges, marine piles and other structures to contribute significant strength, without increasing the dead load supported by the structure.
MapeWrap C Uni-Ax 600 is a high-strength, uni-directional carbon fiber fabric that, when used with the MapeWrap family of two-component epoxy adhesives, forms an externally bonded fiber-reinforced polymer (FRP) reinforcement system. MapeWrap C Uni-Ax 600 is part of an engineering solution that allows for an increase in the strength of structural elements without increasing the dead load supported by the structure. MapeWrap C Uni-Ax 600 has twice the weight to surface area and twice the thickness of MapeWrap C Uni-Ax 300.
MapeWrap G Uni-Ax is a high-strength, uni-directional E-glass fiber fabric that, when used with the MapeWrap family of two-component epoxy adhesives, forms an externally bonded fiber-reinforced polymer (FRP) reinforcement system engineered to increase the strength of structural elements. When applied to the surface of structural members in buildings, parking garages, bridges, marine piles and other structures, MapeWrap G Uni-Ax improves the seismic performance of concrete columns, masonry and concrete walls, and concrete beam-column connections.
MapeWrap C Bi-Ax is a bi-directional carbon fiber fabric with balanced weight and having a high modulus of elasticity and high tensile strength. Mapewrap C Bi-Ax is suitable for repairing concrete structures and for improving the flexural and shear strength of reinforced concrete elements. It is also used for the confinement of axial- loaded elements (columns, bridge piers, chimneys) subjected to compressive and bending stress, and for seismic strengthening in earthquake areas. MapeWrap C Bi-Ax is installed using the "wet-layup" system where the fabric is saturated immediately before placement and the "dry-layup" system where the fabric is saturated during application.
MapeWrap C 380 Quadri-Ax is a balanced, high-strength, quadric-directional carbon fiber fabric.
MapeWrap Primer 1 is a two-component, super-fluid , solvent-free epoxy resin , formulated for the consolidation and priming of concrete, reinforced concrete, or masonry surfaces before bonding MapeWrap fabrics, Carboplate (TM) plates, or Maperod (TM) rods. MapeWrap Primer 1 is prepared by pouring Part B into Part A and mixing until the resin is completely homogeneous. The mixing ratio is 3 parts by weight of Part A to 1 part by weight of Part B. MapeWrap Primer 1 is then applied by a brush or roller onto a clean, dry and mechanically sound substrate. MapeWrap Primer 1 remains workable for 90 minutes at 73 degreesF (23 degreesC).
MapeWrap 11 Normal-Setting, Thixotropic Epoxy Putty for Smoothing and Leveling Concrete Surfaces. MapeWrap 11 is a two-component, epoxy resin-based product with selected fine-graded aggregates and special additives developed in MAPEI's research laboratories. MapeWrap 11 is used to level concrete or reinforced concrete surfaces that need to be repaired or reinforced by bonding the MapeWrap fabrics, Carboplate carbon plates, and Maperod carbon rods, and as a structural adhesive for the Carboplate and Maperod systems.
MapeWrap 12 Slow-Setting Epoxy Putty for Smoothing and Leveling Concrete Surfaces. MapeWrap 12 is a two-component, epoxy resin for leveling concrete or reinforced concrete surfaces and as a structural adhesive for the Carboplate and Maperod systems. MapeWrap 12 is recommended in hot climates (applications at temperatures > 73 degrees F (23 degrees C), or when leveling large surface areas. MapeWrap 12 is prepared by pouring Part B into Part A and mixing until the resin is completely homogeneous. The mixing ratio is 3 parts by weight of Part A to 1 part by weight of Part B. MapeWrap 12 remains workable for about 60 minutes at 73 degreesF (23 degreesC).
MapeWrap 21 Epoxy Resin for ' Wet-Layup' Saturation of MapeWrap Fabrics.
MapeWrap 21 is a two-component, super fluid, solvent-free epoxy resin product, formulated for the saturation of MapeWrap fabrics, immediately before placing the fabric. The saturation is accomplished by dipping the fabric into a trough or other impregnation equipment. MapeWrap 21 is prepared by pouring Part B into Part A and mixing until the resin is completely homogeneous. The mixing ratio is 4 parts by weight of Part A to 1 part by weight of Part B. MapeWrap 21 remains workable for 40 minutes at 73 degreesF (23 degreesC). The impregnated fabric is applied over the still fresh MapeWrap 11 or MapeWrap 12 , ensuring that it is laid without wrinkles.
MapeWrap 31 Epoxy Resin for ' Dry-Layup' Saturation of MapeWrap Fabrics.
MapeWrap 31 is a two-component, solvent-free epoxy resin product, formulated for the saturation of MapeWrap fabrics during application, using the "dry-layup" system. MapeWrap 31 is prepared by pouring Part B into Part A and mixing until the resin is completely homogeneous. The mixing ratio is 4 parts by weight of Part A to 1 part by weight of Part B. MapeWrap 31 remains workable for 40 minutes at 73 degreesF (23 degreesC). MapeWrap 31 is applied onto the still fresh MapeWrap 11 or MapeWrap 12 with a brush or short bristle roller, and the fabric is then placed over the concrete element, removing any wrinkles.
