Repairing Materials for Defects in Steel

As the saying goes, "Prevention is better than cure", this is so with Civil Engineering  Suuctures too. It is wise to ensure that corrosion resistance is built during the design/construction stage itself, instead of attending to its mal-effects at a later stage by adopting time consuming/ expensive methods.

Objectives

At the end of this unit, you should be able to:

know the various ways of dealing with the corrosion problem,

understand the Coatihgs and protective layers,

analyse Design and construction practices which rnaxirnise the protection afforded by the portland cemknt concrete,

adopt Treatments which penetrate or are applied on the surface (of €he reinforced cmsrete member) to exclude chloride ion from the concrete, andapply the Techniques which prevent corrosion of the reinforcement directly.
