REINFORCED CONCRETE - ENHANCEMENT THROUGH TOPICAL TREATMENTS

This article reviews treatments that can be applied to the surface of reinforced concrete to solve problems that are occurring at depth. The author discusses barrier coating, hydrophobic impregnations, inhibitors, cathodic protection, and strengthening systems. Barrier coatings can prevent additional ingress of damaging materials and provide an improvement in overall appearance of the structure. Hydrophobic impregnations penetrate the concrete and form a water-repellent lining on the surface of the pores (they do not provide protection against standing water, however). Inhibitors are surface-applied materials that soak into the concrete, reach to the surface of the steel rebar, and provide protection against corrosion. Impressed current cathodic protection is the main method of preventing corrosion or reinforcing steel. Strengthening systems usually involve the use of fibers encapsulated in an epoxy resin which is applied to the surface of the concrete. The author concludes that this range of techniques, when properly applied, will produce durable structures for life.
