Abstract
An improved composite material used to connect, strengthen and/or repair concrete. The improved composite material includes a first fiber system including at least one fiber layer. Each fiber layer includes a plurality of fibers. The binding material can be used to optionally secure together the plurality of fibers. The improved composite material is positioned and secured in a slot cut in a concrete structure. The top edge of the improved composite material includes a recess portion.
Claims29
A method for connecting, strengthening, and/or repairing a concrete structure about a gap in said concrete structure, said method comprises:
- a) providing a composite material repair device;
- said composite material repair device includes a first fiber system;
- said composite material has a top edge, a bottom edge, a first top edge end, a second top edge end, a front face, and a back face;
- said top edge includes a non-linear profiled edge that includes a recess portion positioned between said first and second top edge ends;
- at least a portion of said recessed portion is located at a midpoint between said first and second top edge ends;
- a longitudinal length of said recessed portion is 5-60% of a longitudinal length of said composite material repair device that is measured from said first top edge end to said second top edge end;
- a maximum depth of said recessed portion is 5-50% of a maximum height of said composite material repair device as measured from said top edge to said bottom edge of said composite material repair device;
- said first fiber system includes a first fiber layer and a second fiber layer;
- each of said first and second first fiber layers includes a plurality of fibers;
- said plurality of fibers in said first and second fiber layers are connected together by a first adhesive or resin material;
- said first and second fibers layers are connected together by a second adhesive or resin material along all of said longitudinal length of said composite material repair device;
- said first and second fiber layers are continuous along said longitudinal length of said composite material repair device;
- said first fiber system forms at least a portion of said first and second top edges of said composite material repair device and at least a portion of said recess portion;
- said longitudinal length of said composite material repair device is no more than 25 inches;
- a maximum width of said composite material repair device is no more than 0.5 inches;
- said maximum height of said composite material repair device is no more than 6 inches;
- said first and second top edge ends each include a curved surface;
- b) cutting a slot in said concrete structure, wherein said slot intersects and crosses a longitudinal axis of said gap;
- c) inserting said composite material repair device at least partially in said slot;
- and,
- d) inserting an adhesive in said slot that includes at least a portion of said composite material repair device to secure said composite material repair device in said slot.
