1、CONVENTIONAL PRODUCTS:

2、INNOVATIVE PRODUCTS:

SST reinforcing products are designed and sold as a turnkey system that include the carbon fi ber material and epoxy. This assures the fi nal concrete restoration installation will perform as designed. SST products include FRP sheet, carbon laminate, pre-stressing kits and compatible epoxies.

SST offers an innovative FRP sheet system that offers water vapor permeability of the enclosed concrete, allowing the moisture in the concrete to escape; preventing destruction of the repaired concrete due to moisture buildup.

SST's patented pre-stressed carbon laminate system allows for greater utilization of the carbon laminate strength resulting in a stronger repair of the concrete member.

FRP CARBON SHEET WATER VAPOR PERMEABILITY SYSTEMWhen applying FRP sheets in a fully covered reinforcement application, the moisture permeability of the system should be considered to assure that the moisture within the concrete element can properly escape while also preventing moisture from entering from the outside. SST's vapor permeable system allows the installed FRP system to breathe, ensuring the durability of the reinforced concrete. This protects the repaired internal concrete from moisture caused spalling and related damage.

ACI Building Code for Structural Concrete- ACI FRP Guide 440 (Chapter 8.3.3 Durability Considerations)

Any FRP system that completely encases or covers a concrete section should be investigated for vapor pressures and moisture vapor transmission.

Vitruvius (Roman Architect and Engineer, 50 B.C.)

A structure must be permeable to water vapor from the inside to the outside.

FRP SHEET

FRP SHEET

Determination of the water vapor-permeability of a coating

Sd =μH2O×layer thickness (m) < 4m

Sd：Water vapor diffusion resistance of the layer

μH2O：Water vapor diffusion coeffi cient of the coating

SST Resicem μH2O ≈ 3,000~5,000 (FRP thickness 1 mm)

S&P Resin 50/55 (epoxy resin) μH2O = 1,000,000 (FRP thickness 1 mm)

It follows that:of a two-layer FRP coating using SST Resicem, with a total thickness of 0.8 mm (matrix + fi bers),

Sd = 4,000×0.0008 = 3.2m < 4m

• SST Resicem the water vapor-permeability of the FRP system is assured.

Concrete moisture can escape from inside

Outside water vapor cannot enter

NON-PRESTRESSED (SLACK-APPLIED) LAMINATESST's carbon fiber laminates are made of 12k small tow carbon fiber thread and epoxy adhesive in a highly advanced continuous pultrusion production process. The carbon laminate strip is adhered to the concrete surface with our specially formulated epoxy paste assuring a high strength installation. The carbon fiber content of the laminate is greater than 70%. The resulting installation results in substantially increased bending capacity of the reinforced concrete member.

1. Removal of concrete up to the rebar 2. The base plate is grouted in with SST Resin 220

3. The laminate is epoxied onto the bottom surface and the top plate epoxied and anchored over the end of the laminate

The following table sets out typical uses for the various products

CARBON LAMINATE

A standard non-pre-stressed laminate system does not fully utilize the additional potential strength in the carbon laminate material. The pre-stressed system is installed by anchoring one end of the laminate strip, prestressing the other end with SST's patented installation system, then allowing the epoxy adhesive that is applied to the underside of the carbon laminate to cure. Internal testing has shown up to a 40% increase in the ultimate capacity when using a pre-stressed system versus a slack application system.

SST's pre-stressed laminate system unique designed anchorage plates and hydraulic tensioning equipment allow for efficient installation on the jobsite, resulting in a maximum increase in the bending strength of the concrete member.

Pre-stressed System Installation Features：

Safe and Reliable: 1. This system has been successfully installed in thousands of jobsites around the world.

Easy to Install:2. With the unique patented anchorage plate system, job site installation can be accomplished in minimal time. It can be used in small work spaces and causes minimal damage to the existing concrete surfaces.

Reliable Anchorage System:3. This system has been laboratory and job site tested for reliability and safety.

A Complete System:4. SST provides everything to complete the job- the installation kit, carbon laminate and specially formulated epoxy; assuring a comprehensive solution for even the most demanding reinforcement challenges.

Versatile:5. Is especially useful on long-span RC elements due to higher defl ection and fl exural resistance.
