Title of the articleInvestigation of the effect of thickenings in fiberglass reinforcement on adhesion to concrete
Abstract.Problem statement. The combined action of concrete and reinforcement is mostly ensured by adhesion. It is proposed to increase the cross-section of fiberglass reinforced polymer (FRP) locally to achieve a higher bond strength. Thick places are creating during the production of FRP by intervening scraps in the structure on reinforcement while threads are pulling through a die hole. Results. The main results of the work consist of the experimental study of a new profile of FRP with the determination of the strength and deformation characteristics of the adhesion, performed by GOST 31938-2012. Conclusions. The importance of the research results obtained for the construction industry is that bars locally increased cross-section have 67.8 % more adhesion effect compared to similar reinforcement without thickening and 46.6 % more adhesion compared to other manufacturers. This solution can be used in cases where the length of the embedment in concrete is not sufficient to transfer forces, so it is an alternative to hooks, nuts, etc. used for steel reinforcement.
Keywords.fiberglass reinforced polymer, adhesion, anchoring, thickening, testing, strength.
