Abstract

A method of reinforcing a structural support, includes applying a reinforcement system comprising an AR-glass fibrous layer embedded in an inorganic matrix to the structural support. The AR-glass fibrous layer has a sizing applied thereon, and a resinous coating applied is applied over the sizing. The inorganic matrix is adherent to the resinous coating and the resinous coating is adherent to the sizing.

Claims

1. A structural support system comprising:

a structural support, and

a reinforcement system adhered to the structural support, said reinforcement system comprising;

an AR-glass fibrous layer embedded in an inorganic matrix, wherein said AR glass fibrous layer has a sizing applied thereon, the sizing comprising an epoxy polymer, vinyl and amine coupling agents, and a non-ionic surfactant, and

a resinous coating applied over said sizing, the coating comprising acrylic, said inorganic matrix being adherent to said resinous coating, and said resinous coating being adherent to said sizing.

2. The support system of claim 1, wherein the inorganic matrix comprises a cementitious material.

3. The support system of claim 1, wherein the AR-glass fibrous layer is formed by weaving, knitting or adhesive-bonded cross-laid fibers.

4. The support system of claim 1, wherein the fibrous layer is formed from continuous or discontinuous fibers randomly oriented in a non-woven mat.

5. The support system of claim 1, wherein the inorganic matrix material includes chopped alkali-resistant fibers.

6. The support system of claim 1, wherein the inorganic matrix directly adheres to the structural support.

7. The support system of claim 1, wherein the structural support comprises an unreinforced masonry.

8. The support system of claim 1, wherein the structural support is comprised of bricks.

9. The support system of claim 1, wherein the structural support is comprised of concrete.

10. The support system of claim 1, wherein the structural support is comprised of cement.

11. The support system of claim 1, wherein the inorganic matrix comprises a cementitious material and chopped AR-glass fibers.

13. The reinforcement material of claim 1, wherein said inorganic matrix includes a resin which forms an adhesive bond with said resinous coating.

14. The reinforcement material of claim 1, wherein said sizing and said resinous coating form a chemical bond.

12. A structural support system comprising:

a structural support, and

a reinforcement system adhered to the structural support, said reinforcement system comprising an AR-glass fibrous layer embedded in an inorganic matrix, wherein said AR glass fibrous layer has a sizing applied thereon, and a resinous coating applied over said sizing, said inorganic matrix being adherent to said resinous coating, and said resinous coating being adherent to said sizing,

wherein the coating comprises PVC plastisol and the sizing comprises anhydrous polymerized epoxy amine, vinyl and amine coupling agents and a non-ionic surfactant.
