Modification Of The Epoxy Binder For Glass and Basalt Rebar. Mechanical Test Results

The paper presents the results of experimental studies on the modification of the epoxy binder LE-828 for the manufacture of glass and basalt rebar. The nano-size silica powder is used as a filler. The filler mass content ranged from 0% to 2%. It is shown that the nano-disperse filler introduced in the binder leads to the increasing breaking stress and tensile strength by 33% and 34%, respectively; the failure strain increased by 39% at the filler mass content of 0.6%.
