Influence of Epoxy Glue Modification on the Adhesion of CFRP Tapes to Concrete Surface

“…In physicochemistry, adhesion is one of the most difficult phenomena to define unambiguously. According to [ 1 , 2 , 3 , 4 , 5 ], it is a series of phenomena that may occur at the contact of surfaces of adjacent materials. In Latin, adhesio means adhering, sticking [ 3 ].…”

“…Importantly, the individual definitions complement each other. Over the years, the research on adhesion, the development of which was possible owing to the development of the field of science, the so-called surface physicochemistry [ 1 , 2 , 7 ], have resulted in an increasingly consistent but also multi-directional definition of adhesion [ 4 , 5 , 8 ]. The definition of McBain and Hopkins [ 9 ] was developed as one of the first.…”

“…Hence, several models of adhesion are adopted in the literature, along with the main factors determining them. The most common division in the literature is presented in Figure 1 [ 3 , 4 , 6 ].…”

“…As can be seen from the diagram, apart from the original (first developed mechanical model), which depends mainly on the interlocking of rough surfaces of the materials to be joined [ 2 , 4 ], other factors also have an influence on the adhesion. The proper adhesion depends primarily on the physico-mechanical interactions, in particular the possible occurrence of chemical bonds (according to the types shown in the diagram) between the atoms located on adjacent surfaces.…”

“…Other adhesion mechanisms most frequently described in the literature are: electrostatic adhesion resulting from the interactions of charges at the interface [ 3 , 4 , 17 ], diffusion consisting in joining materials as a result of mutual passage and permeation of charges between surface layers [ 2 , 18 , 19 ], the theory of weak boundary layers taking into account the possibility of the occurrence of factors weakening adhesion on the joined surfaces, i.e., surface pores, impurities, voids [ 2 , 3 , 4 , 20 ] and the acid-base theory described in [ 2 , 3 , 4 , 21 ] relating to the acceptor—donor capacity of chemical compounds [ 2 , 15 , 21 ].…”
