Abstract
A fiber reinforced polymer strengthening system having a concrete structural member having at least one outer facing surface. At least one pultruded element is located on the outer facing surface of the concrete structural member, the pultruded element containing a matrix material having a Tg of at least about 110° C. and a plurality of fibers having a tensile strength of at least about 300 MPa and an operating temperature of at least the Tg of the matrix material. Also located on the outer surface of the concrete member and at least partially covering the at least one pultruded element is an inorganic binder comprising an inorganic material having an operating temperature of at least about Tg of the matrix material of the pultruded element.
