Abstract
The present invention is a method for reinforcing a cementitious structure by contacting the structure with a fiber reinforced patch, wrapping, or insert contacting a heat-curable adhesive layer, then heat curing the adhesive. The patch or wrapping contains a fiber reinforcing layer affixed to a curable adhesive layer and the insert is typically an elongated fiber-reinforced composite surrounded by the heat curable resin and impregnating aligned fibers that extend longitudinally through the length of the composite.
Claims15
A method for repairing or reinforcing a cementitious structure comprising the steps of a) applying to the structure a multilamellar patch or wrapping that contains a fiber reinforcing layer in contact with a curable adhesive layer so that the curable adhesive layer is in contact with the structure;
- and b) curing the curable adhesive layer to bond the multilamellar structure to the cementitious structure.
A method of reinforcing a cementitious structure comprising the steps of a) forming a groove at the surface of the structure;
- b) inserting into the groove a fiber-reinforced composite surrounded by a heat-curable resin;
- and c) heat curing the resin so that the composite bonds to the structure.
