Original Abstract

Methods of external strengthening of concrete make use of elements of very high tensional strength glued on tensioned surface of it. These elements may be of metal, carbon fibers (CFRP), glass fibers (GFRP) or others, being ordinarily of very good mechanical properties. Presentation of several short-term experiments as so as long-term experiments executed either in past or just now being in motion are briefly descript. Short of history is also included. Some elementary knowledge about this know-how is described here with brief categorization of used materials. But these high strength elements are attached to concrete most frequently by epoxy resins. However, epoxy resins are of low Youngs modulus and therefore a higher rate of creep may have influence on long-term behavior of such external strengthening. In order to verify this idea experimentally a special space saving arrangement of tests is put on in part of this paper. General reference to existing practical realizations is added, too.
