Abstract
A method for treatment of carbon fibers for reinforcement comprises the step of coating or impregnating carbon fibers with an emulsion of epoxy resin having colloidal silica added thereto so as to harden the same. The carbon fibers treated in this way exhibit high bonding strength with respect to a concrete matrix, making it possible to obtain excellent carbon fiber reinforced mortar and concrete.
