Some practitioners strongly feel that the quality of the patch repair is of far more important than the relative resistivities of the parent concrete and patch repair material and that as long as metallic conductors (including carbon) and epoxy concretes are excluded that repairs will do their job while cathodic protection does its job.

Filler treatment in filled polyester or epoxy coatings (epoxy concrete patching formulations). 

For overall corrosion resistance the epoxy novolacs are somewhat superior to bisphenol A. However, for strictly atmospheric corrosion resistance bisphenol A is satisfactory. The filler most often used with epoxy concretes is silica along with an amine hardening system. This combination provides a polymer concrete with outstanding physical properties and moderate overall corrosion resistance. However, it is perfectly suitable to resist normal atmospheric corrosion (see Table 10.2).

Analysis of the overall desirability behaviour for two polyester concretes and two epoxy concretes is presented. Results of the statistical and graphical analysis can be treated as a quantitative representation of the forecasts based on the theoretical considerations of the material model for resin concretes. 

In three of the four considered cases the experimental domain includes the point related to the most desirable concrete.For all the considered concretes an optimal microfiller content is about twice higher than the resin binder content. This result corresponds to conclusions obtained on the basis of theoretical considerations when one assumes obtaining concrete with resin binder exclusively in "ordering state"[5]. Values of the overall desirability for the polyester concretes are greater than those for the epoxy concretes.lt is probably connected with lower viscosity of polyester binder and in consequence with better homogenization of the composite.
