摘要：The research was conducted in order to determine the effect of the polymer additive on the adhesion between the fiber and the cement-sand matrix, since the involvement stage of the composite fiber material directly depends on the adhesion value between these dissimilar components. Throughout the study, the issue at stake was to determine the optimal method for adhesion increasing to assess its effectiveness, and also to carry out an experiment and obtain actual numerical change values of the adhesion to carbon fiber (the assessment was made considering changes of the strength parameters). According to the results of conducted testings, the tensile strength during the bend almost wasn’t affected in resin-injected samples with the amount of fiber of 1 and 3% (increments of 12.7 and 15.7%, respectively). Despite this, the combined application of a resin with the same amount of fiber gave the increments of 34 and 20%, respectively. Conclusions are drawn about the prospects of polymer additives usage in carbon fiber reinforced concrete. The mechanism of increasing the carbon fiber involvement in the composite behavior is considered, the positive effect is confirmed by the study of the chemical processes that arise during the interaction of fiber and water-soluble resin.
