Abstract:

In civil engineering applications, in the past 15 years epoxies have become widely used and have given excellent performance in floor surfacing, corrosion protection, repair of cracked structures, glueing together of precast concrete pieces, etc. But discouragingly often, epoxies have not performed as expected. Among reasons: epoxy formulation not matched to job at hand; epoxy mixture prepared or applied incorrectly, or (a common mistake) the surface to which the epoxy was to be applied was not prepared properly. Here is an introduction to epoxies�� range of properties, how to match properties to job at hand, some types of problems, their causes, and factors to consider before using an epoxy. Case histories�� some successful and some not�� indicate range of applications, and some classes of problems and their causes.
